Two teenagers are facing life behind bars after being convicted of murdering an innocent schoolboy stabbed to death in Brixton.

Kwame Ofosu-Asare, 17, became caught up in a fight between gangs when he was mistaken for a rival.

He was killed in daylight while he was walking with a friend through the Moorlands Estate in March.

Nelson Idiabeta, 18, of no fixed abode, and Nathaniel Okusanya, 19, of Vibart Gardens, Lambeth, were found guilty at the Old Bailey today and remanded in custody for sentencing tomorrow.

Crispin Aylett QC, prosecuting, earlier told jurors: “Kwame’s death was but a part of a poisonous and senseless feud between two rival gangs of youths in south London.

“Kwame was in fact not a member of either gang.

“He was killed for no reason other than that his murderers had come upon him on an estate which they considered to be enemy territory, and at a time when they were looking to take revenge for the stabbing of one of their own only hours earlier.”

Kwame was stabbed repeatedly in the back and received a total of 14 wounds while walking in Adelaide Close with a friend.

The boys tried to get away by going into a side road where the friend’s aunt lived, but the aunt was not home and they were trapped in a cul de sac.

Mr Aylett said the attack on Kwame had its roots in a feud between the TN1 (Trust No-One) gang from the Tulse Hill area of south London and Brixton-based GAS (Guns and Shanks).

Idiabeta and Okusanya were members of the TN1 group out to avenge one of their number who had been stabbed in a bus garage attack carried out by GAS earlier in the day.

On the day of the killing, Kwame and his friend had gone to a music studio in Brixton.

They were about to head to Denmark Hill train station when the friend remembered he had to collect a bag from an aunt who lives on the Moorlands Estate.

Kwame’s father Kwaku, a sports journalist, told the court in a statement that his son was full of potential.

He was in the sixth-form of Forest Hill School and excelled in sport, music and acting and had great ambitions to make something of his life.

Mr Ofosu-Asare said: “Kwame was a very vibrant, energetic and enthusiastic boy.

“His brother and sister are struggling to cope with his death. All our lives have been ruined.”
