The stabbing is the latest in a spate of violent teenage deaths

A teenager killed in south London died from a single stab wound to the heart, post-mortem tests have revealed.

The 18-year-old, was attacked by up to eight males in Guildford Road, Stockwell, on Thursday.

Friends of the teenager said he may have been attacked over a minor insult during a water fight at the Holland Park fair.

A 16-year-old boy who was arrested earlier in connection with the stabbing is still being questioned by police.

Police said he was arrested at his home in Brixton, south London.

One of the victim's friends left a water gun at the scene of the attack last night.

He said: "The last time I saw him was at the end of this road at around six - he seemed happy.

"We had been to a water fight, along with many others from around London, at Holland Park.

"The next thing I knew was that he had been stabbed."

He is the 21st teenager to be murdered in London this year.
