Christmas Holidays, Group Chats and Knife Images: Why Police Contact Parents in January

Why Knife Images in Youth Group Chats May Raise Concerns

Children often spend more time messaging friends during the Christmas holidays. Group chats may contain jokes, arguments, photographs or videos that parents and schools only become aware of later.

If someone shares a knife image, particularly alongside an aggressive or threatening message, another child or parent may report it to the school or police.

Concerns raised during the holidays may then be addressed when the school term begins in January.

However, a report does not necessarily mean that a criminal offence has taken place.

There are three possible reasons for contact.

• A safeguarding concern arises where adults are worried about a child’s safety or wellbeing. 
• A school disciplinary matter involves behaviour that may breach school rules. 
• A criminal investigation begins where police suspect that an offence may have been committed.

These processes are different, although they can sometimes overlap.

For example, a school may investigate threatening messages under its behaviour policy while also considering whether the children involved need safeguarding support.

If a knife is physically found at school, the situation may be more serious and require immediate police involvement.

Parents should establish the reason for the contact before deciding how to respond.

Does Group Membership Make Your Child Responsible?

Being part of a group chat does not by itself make a child criminally responsible for content that other members have posted. 

The law distinguishes between receiving content and actively participating in criminal behaviour.

For example, your child may have been added to a group without asking or may have seen an image without commenting on it.

That is different from sending a threatening message, encouraging someone to commit an offence or helping another person carry out criminal conduct.

In certain circumstances, someone can be held responsible for a crime they did not personally commit if they intentionally assisted or encouraged it. This is sometimes referred to as joint enterprise.

However, simply being present in a group conversation is not enough.

Forwarding a threatening image, adding an aggressive caption or encouraging others to act may raise different legal questions from passively receiving the content.

Police must consider your child’s individual conduct rather than assume that everyone in the chat was equally involved.

How Messages, Context and Individual Conduct Matter

How authorship and sharing affect the assessment

Prosecutors and investigators look at who sent an image, who forwarded it and who only received it. 

These are different positions and they carry different levels of potential legal exposure. What a child typed alongside an image, including any caption, comment or reaction, may be relevant to any assessment of intent. 

A neutral or alarmed response from a child who received an image is not the same as a comment that endorses or amplifies it.

What makes a communication potentially criminal

Some messages shared online may amount to criminal offences, particularly where they contain threats of violence or other serious harm.

• Sending a threatening communication is an offence under the Online Safety Act 2023. 
• Sending a grossly offensive or menacing message via a public electronic communications network is an offence under the Communications Act 2003. 
• A message must do more than shock, offend or express an unpopular view before prosecutors are likely to treat it as criminal.

The Crown Prosecution Service approach requires prosecutors to consider carefully whether a communication goes beyond being offensive, shocking, banter or the expression of an unpopular opinion before proceeding with a charge. 

Any prosecution must be necessary and proportionate. 

These thresholds matter because much of what circulates in youth group chats, even content that is unpleasant or inappropriate, will not meet the standard required for a criminal charge.

The knife image itself: image sharing versus physical possession

Sharing or receiving a photograph of a knife is not the same as physically possessing one.

Carrying certain knives or bladed articles in public without a lawful reason can be a criminal offence.

However, a photograph of a knife does not establish that your child possessed or carried the weapon.

There is also no general rule making the mere receipt or viewing of an ordinary knife image in a private group chat a criminal offence.

Whether sharing such an image is criminal depends heavily on the content, any accompanying caption or threat and the context in which it was sent.

A solicitor with youth crime experience can assess the specific content and context in your child’s situation and advise on whether any offence is likely to have been committed.

What to Do if Police or School Staff Contact You About Youth Group Chats

Stay calm and ask what the contact is about

When police or school staff first make contact, ask clearly whether this is a safeguarding referral, an informal school conversation or a formal police investigation. 

The nature of the contact determines the appropriate response. You are entitled to that information and it will shape every decision that follows.

Do not ask your child to change, delete or explain messages yet

Do not instruct your child to delete messages, deactivate accounts or contact other children involved in the chat. 

Doing so risks interfering with evidence and could create additional legal difficulties for your child and potentially for you. 

This is about protecting your child’s position until you have proper advice, not about assuming guilt.

Seek legal advice before any formal interview

If police wish to speak to your child formally, obtain advice from a youth crime solicitor before agreeing to any interview. 

Legal advice at the police station is free under the duty solicitor scheme and is available to anyone regardless of financial means. 

This applies whether your child is under arrest or is invited to attend voluntarily.

Distinguish a voluntary interview from an informal conversation

Police may invite your child to attend a voluntary interview under caution. 

This is a formal legal process, not an informal conversation. It carries the same right to legal advice and the same requirement for an appropriate adult as an interview following arrest. 

It should not be treated as a friendly chat that can be attended without preparation.

A brief conversation at the school gate or a welfare check by a police officer is a different matter. 

It does not carry the same formal protections, but parents should still treat it with care and should not encourage their child to make detailed comments before receiving advice.

Preserving Youth Group Chat Records, Images and Relevant Evidence

Preserve the complete chat history, including timestamps, participant lists and any surrounding messages, before any update, auto-delete setting or platform archiving removes it.

Context matters considerably. Messages before and after any image was shared may show what was actually said, by whom and in what tone.

When taking screenshots of youth group chats, capture the full thread rather than isolated images. A partial record can be misleading and may not accurately represent your child’s position or involvement.

Preserved records should be shared with your child’s solicitor, not sent to police or other parents before you have taken legal advice. 

A solicitor can assess what is relevant, advise on what should be disclosed and ensure it is handled correctly.

Your Child’s Rights During a Police Interview

The right to legal advice

Your child is entitled to legal advice if police wish to interview them under caution.

This applies whether the interview follows an arrest or your child attends voluntarily.

A solicitor can explain the allegations, advise on the evidence disclosed by police and help your child understand how to respond.

The solicitor represents your child’s interests and can provide advice independently of parents or other adults.

The appropriate adult requirement

When a child under 18 is interviewed by police, an appropriate adult must be present throughout. This is usually a parent or guardian, though it can also be a social worker or another responsible adult in some circumstances. 

The requirement is a legal safeguard under the Police and Criminal Evidence Act 1984 Codes of Practice. The appropriate adult’s role is to support the child and to ensure the interview is conducted fairly. 

The appropriate adult is not the child’s legal representative and should not answer questions on the child’s behalf. 

If you attend in this role, your function is to be present and supportive, not to speak for your child or intervene in the questioning.

The right to silence

Your child has the right to respond “no comment” to police questions. Whether that is the right approach depends on the specific circumstances, and your child’s solicitor will advise on this before the interview begins. 

In some circumstances, adverse inferences can be drawn from silence when a case goes to court. That is precisely why taking legal advice on this point before the interview, and not during it, matters.

Possible Outcomes, Penalties and Youth Sentencing

No further action

After initial inquiries, police may decide there is insufficient evidence to proceed or that a criminal response is not proportionate. 

The matter may be closed, or it may be referred back to safeguarding channels. 

This is a common outcome, particularly where a child’s involvement in youth group chats was peripheral and no threatening conduct is identified.

Safeguarding referral and early intervention

Where a child is assessed as being at risk or as having vulnerabilities, the response may be a referral to children’s services or a Youth Justice Service intervention rather than prosecution. 

Government guidance makes clear that children found to have broken the law in connection with knives should receive tailored support and interventions from a Youth Justice Service. 

Safeguarding action is focused on the child’s welfare, not on punishment.

Out-of-court disposals

For children and young people, police and prosecutors have a range of options that fall short of prosecution. These include community resolutions, youth cautions and youth conditional cautions. 

These disposals do not result in a criminal conviction but they may be recorded and may be relevant in some future contexts. A solicitor can explain what any proposed disposal means for your child before you agree to it.

Prosecution and youth court

If police believe there is sufficient evidence of a criminal offence, the case may proceed to prosecution.

Most criminal cases involving children aged 10 to 17 are dealt with in the Youth Court.

The Youth Court considers the offence, the child’s age, personal circumstances and any previous offending.

Youth sentencing places particular emphasis on rehabilitation and preventing further offending.

The available penalties depend on the specific offence.

For example, carrying a knife in public is treated differently from sending a threatening online message, and the evidence required for each offence is not the same.

More serious cases may involve different procedures or sentencing powers.

A solicitor can explain the possible outcomes based on the actual allegation rather than assuming that a knife image will automatically lead to serious criminal penalties.

Speak to a Solicitor About Your Child’s Involvement in Youth Group Chats

If police or school staff have contacted you about knife images or threatening messages in your child’s group chat, it is important to understand what your child is alleged to have done and what process is being followed.

Not every concern leads to a criminal investigation, but messages shared online can have serious consequences where threats or other unlawful conduct are involved.

Our criminal defence team can advise on your child’s rights, assess the circumstances and explain what to expect if police wish to conduct an interview.

We can also help you understand the available options and the steps needed to protect your child’s position.
