The mother of a London teenager stabbed to death in an apparent “postcode” killing has prayed at the scene of her son’s murder.

Kwame Ofosu-Asare, a 17-year-old Christian, was killed at the Moorlands Estate in Brixton on 2 March. His mother, father and around 30 relatives and close friends gathered at the spot where he died before attending his funeral on Friday.

His mother, Nana Konto, was seen dropping to her knees as she and other members of the group prayed.

They were joined by a church leader who pleaded for an end to gun and knife crime in the capital.

Bishop Kwaku Frimpong-Mason said: “Knife and gun crime in London has to come to an end. It is destroying our communities.”

Kwame, a keen footballer, was born in Ghana but grew up in London and was living in Hither Green. He was on his way to visit a friend’s aunt in Brixton after recording a track at a music studio when he was stabbed to death.

He reportedly “detested” gangs.

His mother said: “In times like these the best I could do was to go down on my knees and offer a prayer to God.”

The funeral service was joined by the Ghanaian ambassador to Britain, Labour peer Lord Boateng, Lewisham Mayor Sir Steve Bullock and local MP Heidi Alexander.

An 18-year-old and 17-year-old have been charged with Kwame’s murder.
