A 13-year-old boy has been charged with killing a 14-year-old who died after he was stabbed in north east London.
Paul Erhahon died in his mother's arms after an encounter between groups of young people on Friday night.
His friend, who has not been named, was also badly injured and is being treated in hospital.
The 13-year-old will appear in court on Tuesday charged with Paul's murder. Police are still questioning two other boys, both aged 14, about his death.
It's important to remember that knife attacks like this one are rare and police will be doing all they can to catch the people responsible.
