A 14-year-old girl was sexually assaulted in Oxford yesterday as she waited for a bus.

The girl was at the bus-stop at the junction of Cowley Road and St Nicholas Road, Littlemore, at about 8.40am.

A man approached her and grabbed her by the shoulders and sexually assaulted her. The girl struggled free and ran away.

Pc Tim Harding, of Thames Valley Police, who is investigating the incident, said: "The girl was not injured but was left shaken by the attack.

"The man was very distinctively dressed in a black tracksuit and black balaclava covering his face. He has tanned hands. Other people must have seen him.

"If you saw what happened or have any information that would help our inquiry then please contact me immediately."
