A woman has been raped by a group of men in a churchyard in Banbury.

The woman, in her 30s, was attacked in the grounds of St Mary’s Church and the surrounding area of the town centre in the early hours of Sunday morning, Thames Valley Police said.

The force is appealing for another woman, who may have tried to help the victim, to come forward.

Det Sgt Mark Personius said an investigation into the “horrific crime” was under way to identify the offenders. The victim is being supported by specially trained officers.
