Man quizzed over boy's stab murder
A man has been arrested by detectives investigating the murder of a 17-year-old boy.
Kwame Ofosu-Asare was found with fatal stab wounds in Adelaide Close on the Moorlands Estate in Brixton, south London, during Friday's evening rush-hour.
A 22-year-old man is being held after a dawn swoop by officers in south London, Scotland Yard said. The suspect remains in custody.
Police carried out a string of raids in recent days as part of a "robust" response to a spate of stabbings in the area.
Eight south London addresses were targeted on Tuesday with four male youths questioned for conspiracy to commit grievous bodily harm.
Chief Superintendent Matt Bell said: "Lambeth borough is committed to reducing serious youth violence and gang activity and we felt it vital that we take robust and prompt action in order to pre-empt any potential future violence."
Kwame and a friend were chased by two knifemen, police said.
Officers are investigating whether the killing is linked to another stabbing on Friday when a 17-year-old boy was attacked outside Norwood bus garage, Ernest Avenue, West Norwood, at around 1.15pm.
There were also a number of gang-related street attacks in Lambeth on February 25, the force said.
Kwame, who lived in Catford, south-east London, was en route to hospital when he died in the ambulance.
