Rapper knifed to death had been cleared of killing teen
A London drill rapper who was stabbed to death had recently admitted the genre was contributing to violence in the capital.
Moscow17 rapper Incognito, whose real name is believed to have been Siddique Kamara (23), was knifed in Camberwell, south London, on Wednesday evening.
He died at the scene and two other males, aged 16 and 31, were taken to hospital with non-life-threatening stab wounds, Scotland Yard said.
Two men, aged 18 and 19, were arrested nearby on suspicion of murder.
The attack happened a short distance from the victim's family home, with his father Lamin Kama saying: "Our family are in a lot of distress at the moment."
His son leaves behind three brothers, he told reporters.
Another member of the Moscow17 collective, 17-year-old Rhyhiem Ainsworth Barton, was found fatally shot on the same street in May.
The group's tracks have had hundreds of thousands of views on YouTube and include lyrics hostile to long-running rivals Zone 2 from Peckham.
Earlier this year Mr Kamara and another member of Moscow17 were cleared at the Old Bailey of murdering teenager Abdirahman Mohamed, a brother of a member of Zone 2.
In one track Moscow17 told Zone 2 to "check the scoreboard", while another asked: "How you gonna make it even?"
A Zone 2 lyric in response told their rivals they would "roll up and burst them".
Kamara posted on Instagram in early July saying: "Keep Hearing I'm The Next Big Thing, Just Gotta Stay Alive & Out Of Jail", and had recently said on Twitter: "My Part Of My Hood Is Tragic Right Now ... I Walk With Allah Daily I'm Blessed."
Metropolitan Police Commissioner Cressida Dick has called on social media platforms like YouTube to remove videos that glamorise violence and, in an interview with Link Up TV earlier this year, Incognito admitted drill music was fuelling violent crime in the capital.
"You see with the crime that's happening right now, music does influence it. You've got to put your hands up and say drill music does influence it," he said.
"But knife crime and gun crime has been going on way before drill music, so if you want to talk about 10 years, 20 years, people were still getting cheffed up (attacked with knifes)."
The police have said that, while they keep an open mind as to the motive, one line of inquiry is that it is gang-related.
