Three sixth-formers were attacked with a blade in Stratford this morning by a man demanding they hand over their mobile phones.

The incident, which occurred at before 11am in the High Street, left one boy with injuries to his ear requiring stitches. A second boy also sustained a cut.

The teenager, a student at the London Academy of Excellence, in Stratford, was with two friends during breaktime when they were approached by a male who demanded their mobile phones.

The man attacked them with a blade and the three teenagers ran to their college where the emergency services were called at around 10.50am.

A spokesman for the police said a teenage boy had sustained head injuries which were not thought to be life threatening.

Robert Wilne, head teacher at the academy, said both injured boys were taken to hospital accompanied by members of staff. Both were fine and all three would be in school on Monday.
