A poll has shown the majority of teens in south west London fear becoming a victim of knife crime.

A survey of 501 people aged between 13 and 18 living in Croydon, Lambeth, Brent, Hackney and Southwark showed that 55 per cent of youngsters are worried they could be affected by knife crime.

The poll, commissioned by BBC London, also revealed that 75 per cent of them do not think London’s mayor, Boris Johnson, will be able to reduce stabbings.

And the number of teens who said they knew a victim of knife crime increased 33 per cent on the same poll’s results last year - to 45 per cent.

This year 21 teens have died in the capital following violent attacks – including Frederick Moody-Boateng a Kingston College student found stabbed to death in South Lambeth on July 17.

And Shakilus Townsend, a 16-year-old, died after being stabbed in Beulah Crescent, Thornton Heath, on July 3.

Six teens have been charged with his murder and remanded in custody to appear before the Old Bailey on October 16.

The survey was carried out by ComRes between July 21 and 23.
