Seventh teenager held over stabbing

A seventh teenager has been arrested in connection with the death of a 15-year-old boy who was stabbed as he arrived for school in what is thought to have been a targeted gang attack.

The youth was one of four being questioned by detectives yesterday about the murder of Zac Olumegbon, who was ambushed on Friday outside Park Campus School in West Norwood, south London.

Three others were released on bail. Detectives revealed yesterday that the stolen car used by the youths suspected of carrying out the attack was found in Stockwell. A post-mortem examination has confirmed that Olumegbon died from stab wounds. A friend who was with him was also stabbed, but less seriously. Park Campus specialises in educating some of London's most troubled children.
