A 15 year-old boy has been charged with murder after a stabbing attack in east London.
It comes after police were called on Friday, just before midnight, to reports of men armed with machetes near to Dagenham Heathway Underground Station.
Scotland Yard said the teenager, who can not be named for legal reasons, has also been charged with attempted murder and possession of an offensive weapon.
He is to appear at Wimbledon Magistrates’ Court on Thursday.
