A third youth has been charged with the murder of 15-year-old Zac Olumegbon who was stabbed to death as he arrived for school.
The 16-year-old will go before Sutton Youth Court today where he will also face a charge of causing grievous bodily harm to a 14-year-old friend of Zac's. He cannot be named because he is a juvenile.
Zac died from multiple stab wounds when he was attacked outside Park Campus School in West Norwood, south London, a week ago. At least four suspects were said to be involved.
Two other youths, aged 16 and 17, have already been charged with Zac's murder and appeared in court on Wednesday. Another two teenagers, also aged 16 and 17, have been released on bail while detectives continue investigating the attack. None can be named.
