Negus McLean murder appeal pt 2

Detectives are offering a £20,000 reward in a bid to catch the killers of 15 year-old schoolboy Negus McClean. The teenager was stabbed to death after being chased by a group of masked youths in Edmonton, north London, on Sunday 10 April, 2011. This CCTV footage shows the suspects cycling together through traffic before the murder. They then spot Negus and his brother on the other side of the road and give chase. Negus was beaten with metal poles before being stabbed in the thigh and chest with such force that the blade snapped off in his body. http://www.murdermap.co.uk/pages/cases/case.asp?CID=315375561&VID=541&Case=Teenager-stabbed-in-Edmonton:-Negus-McClean
