Police say the man is short and of a slim build, with very short dark hair.
Investigating officer Detective Chief Inspector Bruce Riddell of the Oxford Investigation Hub, said: “This is understandably a very distressing incident for the victim in this case.
“We believe that someone may have seen this offender before or after this incident around the area of Divinity Road in the early hours of this morning.
