Kiyan, a tall, muscular boy, was a talented football player
KiyanÃ¢Â€Â™s death comes as the government is making efforts to crack down on the growth of knife crime. Home Office figures for England and Wales show the number of people arrested for possessing an offensive weapon other than a gun have risen by 46% to 35,727 in the past five years.
Knives are a common weapon in this category and 29% of the 820 murders last year were carried out using a sharp instrument.
There were 12,211 knife offences in London, including murder, serious assault, robbery and possession of an offensive weapon. Robbery and assault accounted for the largest proportion of offences.
