Quamari Barnes was stabbed outside his school in Willesden.
A 15-year-old boy has been arrested on suspicion of murder after a boy of the same age was stabbed outside a north-west London school as his fellow students looked on.
Quamari Barnes was attacked while waiting at a bus stop at about 3.30pm on Monday, shortly after the end of the school day at Capital City academy. He was taken by ambulance to a central London hospital where he died.
According to a family friend he was threatened at a bus stop and his assailant chased him as he fled towards school for safety, but the motive for the attack is not yet known.
He is the second London teenager in four days to be fatally wounded in a knife attack. On Friday Djodjo Nsaka, 19, a student at Middlesex University, was found stabbed a few miles away near Wembley stadium.
Throughout Tuesday morning Capital City academy pupils emerged from the school to lay flowers and notes at the entrance gate, clutching each other tearfully or standing quietly together.
One note read: “Quamari was the most positive and energetic person I have ever met. He brought life into everyone’s lives. ‘When one door is closed you know another one is open’ – Bob Marley.”
On Twitter he was celebrated as a “bubbly, happy and also cheeky little boy”.
