A rapper with a “drill” music group was stabbed to death yards from his front door amid fears of an escalation in a bloody gang feud.

Sidique Kamara, the 23-year-old father of a four-year-old daughter, was found fatally injured outside a block of flats in Camberwell.

He was attacked just yards from where 17-year-old Rhyhiem Ainsworth Barton, a fellow member of the “drill” group Moscow17 was shot dead in May.

The pair were pictured alongside Capital XTRA DJ Tim Westwood in a promotional image released in April last year.

Although wearing balaclavas and scarves, friends said Kamara - who performed under the name Incognito - is instantly recognisable from the trademark Arsenal medallion he wears in rap videos on YouTube.

Two other men, age 16 and 31, suffered serious stab wounds and were rushed to hospital in the attack at 7.20pm last night.

The killing came just a day after Met Commissioner Cressida Dick said she believed the rate of violent crime in London was beginning to “stabilise”.

Five people were killed as a result of violence in London last month, compared to 18 in both February and March.

The Moscow17 group’s music label tweeted last night: “Today we have taken a very sad loss.. we ask for all prayers to be directed towards him and his family.”

The death will raise further questions over drill music’s role in glorifying and inciting violence.

The genre, which originated in Chicago, has been criticised by police for its violent lyrics and the Met has successfully applied to ban some groups from performing on YouTube amid fears they are inflaming gang tensions.

Witnesses to last night’s attack in Camberwell told how the men were ambushed by attackers who arrived at the scene in Warham Street on the Brandon estate on Boris bikes.

Primrose Angelique, who saw the aftermath, told the Standard: “I saw them cutting his clothes off him. He was on the ground, there was blood.

“As I watched there was surge of girls that came through. It looked like there was blood on their clothes. Everyone was screaming.”

An off-duty nurse ran down to him with a jacket to stem the blood coming from his side.

She said: “Two young girls ran over to him and gave him CPR whilst I was on the phone to the ambulance.

“He was still breathing and there was no one else around. I tried to stop the blood gushing. He was dying, he couldn’t say anything.”

Kamara, an Arsenal fan, was the youngest of three siblings and had a four-year-old daughter, a family friend revealed today.

She told the Standard: “He was like a son to me. I heard shouting and came down and saw him lying on the floor stabbed.

“His mother was in shock last night I still can’t believe it. These boys never think of the mother’s pain that is left behind.”

The killing is the 88th murder in London so far this year and brings the total number of young people aged 25 or under who have died violently to 33.

Kamara’s killing also comes exactly a week after 18-year-old Latwaan Griffiths, a rapper from the drill group Harlem Spartans, was stabbed to death less than a mile away in Denmark Road.

On July 22, a 25-year-old man suffered non-life threatening injuries after being stabbed outside the Brandon Estate, where Moscow 17 are based.

Detectives are investigating if the latest attack is part of an escalating gang feud in south London.

The day before his death, Kamara tweeted: “My Part Of My Hood Is Tragic Right Now ... I Walk With Allah Daily I’m Blessed.”

In June, Kamara was interviewed about the influence of drill music on violence on London’s streets and admitted it is leading to violence - but said that young people in deprived areas of London have nothing else to turn to.

He said: “But people want to use an excuse now. The government can’t solve the problem. They could bring out youth clubs, you could invest into many other things to help the community, but no you just don’t want to do that - you want to use an excuse and blame drill.”

The rapper was cleared of murder at the Old Bailey in January after being accused of the gang murder of an alleged rival.

Kamara and a co-defendant were alleged to have “executed” Abdirahman Mohamed for apparently laughing at one of their friends.

Kamara claimed he had been deliberately misidentified and both were found not guilty.

Last night residents spoke of their fear that the latest killing would lead to further violence.

Marisa Clacey, 36, who works at the Golden Goose pub yards from the scene, said: “This is not going to stop. There are a lot of gangs round here. Everyone is carrying knives, everyone is bound to use them.

“Everyone round here is scared. All the young boys I know are scared for their lives.”

::Two men, aged 18 and 19, were in custody being questioned on suspicion of killing Kamara.
