A Hendon shop owner has been prosecuted after selling a kitchen knife to an undercover 15-year-old during a Barnet Council test purchase.

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.

The sale took place during an undercover operation in December 2025. The legal age to buy a knife in the UK is 18.

The shop owner, Mustafa Deger, pleaded guilty at Willesden Magistrates Court.
The penalty ordered by the court totalled £4,100.
Barnet Council says residents can report concerns about local business practices to Trading Standards.
Knives can be disposed of through surrender bins when wrapped securely and taken directly there.

Court penalty after Brent Street test purchase

Barnet Council said the prosecution followed a test purchase at Good for You, a shop on Brent Street in Hendon. Deger was caught selling the knife to the teenager during the council operation.

The case was heard at Willesden Magistrates Court, where Deger pleaded guilty in May. The court ordered him to pay fines totalling £4,100.

Knife sales are restricted because retailers must not sell knives to anyone under 18. Shops are expected to have checks in place so staff challenge young buyers and refuse unlawful sales.

Undercover visits during Operation Sceptre

The council’s Trading Standards team carried out a number of undercover test purchasing visits across Barnet as part of Operation Sceptre.

During the visits, police cadets were tasked with trying to buy a knife. The operation tested whether businesses were following the age restriction and whether previous advice from Trading Standards had been put into practice.

Barnet Council said businesses in the borough had already been visited by Trading Standards officers and advised on correct storage and sales techniques for knives. The council also said shops had been given guidance intended to help them maintain a due diligence defence.

For retailers, that means having practical safeguards in place before a sale happens. These can include age-check procedures, staff training, clear refusal policies and secure knife storage.

Reporting concerns about local shops

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

Concerns can also be reported through London Trading Standards. Reports can help enforcement teams identify businesses that may be putting restricted goods into the hands of underage buyers.

The case is part of wider enforcement around knife sales and youth safety in the borough. While one prosecution does not describe the behaviour of all retailers, it shows how test purchasing is being used to check compliance after advice has already been offered.

Knife surrender bins and safe disposal

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

The bins are intended to provide a safe and anonymous way for people to dispose of knives and other bladed weapons.

Anyone disposing of a knife should wrap it first in several layers of cardboard or paper and secure it with sticky tape. The blade should be fully protected and the knife should not be easy to remove from the wrapping.

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

Council warning to businesses

Cllr Sara Conway, Cabinet Member for Community Safety and Chair of the Safer Communities Partnership, said the prosecution showed the council would act against businesses found to be breaking the law.

“This prosecution sends a clear message, that we will not hesitate to act swiftly and firmly against any business found to be breaking the law and compromising the safety of our residents,” she said.

“This is another good result for our Trading Standards team and their long-running partnership with local police cadets.”
