Barnet shop owner fined over knife sale to teen

A Barnet shop owner has been fined after selling a kitchen knife to an undercover 15-year-old during a Trading Standards operation in Hendon.

Mustafa Deger, owner of the convenience and household goods shop Good for You at 114 Brent Street, Hendon, pleaded guilty at Willesden Magistrates Court in May. He was ordered to pay fines totalling £4,100 after Barnet Council brought the prosecution.

The sale took place during an undercover test purchase in December 2025. The legal age to buy a knife in the UK is 18, and councils can take enforcement action when retailers sell knives or other age-restricted products to children.

Undercover knife sale on Brent Street

Barnet Council said the case followed test purchasing visits carried out by its Trading Standards team across the borough as part of Operation Sceptre.

During those visits, police cadets were tasked with attempting to buy a knife from local businesses. One of those attempts resulted in the kitchen knife being sold to the undercover 15-year-old at Good for You in Hendon.

The prosecution means the case has moved beyond a warning or advice visit. Deger admitted the offence in court and was ordered to pay a total of £4,100.

For residents in Hendon and the wider Barnet area, the case is a reminder that age-restricted sales are treated as a community safety matter, not just a licensing or retail compliance issue. Knives sold to under-18s can quickly become part of wider concerns around youth violence, possession in public places and unsafe access to bladed items.

Council says businesses had already received advice

Barnet Council said local businesses had previously been visited by Trading Standards officers to advise them on the correct storage and sale of knives.

That advice included sales techniques and the need for businesses to have a due diligence defence in place. In practical terms, retailers are expected to take reasonable steps to prevent unlawful sales, such as checking age, training staff and controlling how knives are displayed or handed over.

Cllr Sara Conway, Cabinet Member for Community Safety and Chair of the Safer Communities Partnership, said the prosecution sent “a clear message” that the council would act against businesses found to be breaking the law and compromising resident safety.

She said the case was “another good result” for Trading Standards and its long-running partnership with local police cadets.

“Barnet’s community safety partnership is committed to protecting our communities, and ensuring businesses operate within the law,” she said.

Operation Sceptre and knife crime prevention

Operation Sceptre is a wider enforcement and prevention initiative focused on knife crime. In Barnet, the council’s role has included test purchasing, retailer advice and safer disposal options for knives and bladed weapons.

Last year, Barnet Council introduced a permanent knife surrender bin on Bunns Lane, NW7. It also placed a one-day mobile bin in the borough as part of a London-wide initiative funded by the Home Office.

The bins are designed to give people a safe and anonymous way to dispose of knives and other bladed weapons. They are intended for residents who want to remove knives from circulation without handing them directly to police or another authority.

The council’s guidance is that anyone disposing of a knife should first wrap it in several layers of cardboard or paper, then secure it with sticky tape so the blade is fully protected and the knife cannot easily be removed.

Although carrying a knife in a public place is an offence, the council says it is considered reasonable to carry one directly to a knife surrender bin if it has been wrapped safely in that way.

How residents can report concerns

Barnet residents who are worried about how a business is operating can contact the council’s Trading Standards team by email at [email protected].

Concerns can also be reported through London Trading Standards, which handles information about consumer crime and trading offences across the capital.

For retailers, the case underlines the need for active age checks on knife sales, especially where products are sold in general convenience or household goods settings. The offence in Hendon involved a kitchen knife, not a specialist weapon, which is why ordinary retail controls remain central to local prevention work.
