An 11-year-old girl is alleged to have suffered a second sexual assault in six months at a school in east London.

The latest incident happened on Monday in the playground of Downsview special needs school in Hackney.

Last November the alleged victim was one of two girls sexually assaulted by a fellow pupil in the toilets.

Following that incident the school adopted a policy of escorting the children - who all experience learning difficulties - to the toilets, which were also locked during lessons.

A 12-year-old boy was suspended for two days. Sgt Ian Delbarre, of the area's child protection team, said: 'We decided it was not in the public interest to prosecute.' Police are now investigating the latest incident, which concerns two different boys.

A council inquiry, demanded by the girl's parents after the first incident, found the school had 'acted entirely properly'.
