The DJ friend of murdered teenager Carl Beatson Asiedu was also stabbed in the fight outside a nightclub which cost the Norbury teenager his life.

Mr Beatson, an emerging rap artist known as Charmz, and his best friend 19-year-old Peter Lama, known as DJ Sayps, had been one of the main acts at the Summer Vybz event at Club Life nightclub in Kennington.

Both were attacked outside the club and Mr Lama was also stabbed but managed to escape. He was taken to hospital and treated before being discharged.

Daisy Moore, 18, saw her friend Mr Beatson just minutes before he was attacked. She said: “We were all in the party. I was with Carl just before it happened.

“He left about 5am and I came out half an hour later. I saw his friends running, one of them had been stabbed [Peter Lama] and was staggering about outside. The friends drove off to the hospital but the police saw them.”

Friends of the 19-year-old had been trying desperately to drive him to hospital after he had been knifed in the nightclub fight on Saturday morning.

Three cars were pulled over by police after jumping a red light in Baylis Road, Waterloo, where cops discovered Carl’s body bleeding on the back seat of one of them.

The churchgoing teenager bled to death in the back seat of the car before medics could save him.

Police are treating his death, the 11th this year involving young people in London, as murder.

A postmortem examination revealed the teenager had been stabbed to death.

The musician, who performed as Kid n Play with his friend DJ Sayps, had just finished his first year at De Montfort University in Leicester.

He worked part-time at a GP’s surgery in Balham where his mother Hilda worked as a nurse.

Dr Vipen Mittal, who runs the practice, said: “He worked a few hours a week. He was a wonderful boy and a very hard worker.”

The popular teenager was about to release a single, Buy Out Da Bar, and friends are now planning to release the track in his memory.

He had also secured a job as an extra on one of the BBC’s hit children’s programmes MI High.

A spokesman for the BBC said: “Carl was a supporting actor working on the new series of MI High which is being filmed by Kudos Film & TV for the BBC.

“This is the first series Carl had been working on but he was a valued and popular member of our team. The BBC, Kudos and all the production team extend their sympathy to his family and friends.”

Detectives are appealing for anyone who was in the Goding Street area at about 5am and may have witnessed the incident to come forward.

Anyone with information should call Crimestoppers on 0800 555 111.

Two men aged 18 and 20 were arrested in connection with the incident and subsequently bailed.
