POLICE have released images of a man they want to speak to in connection with two assaults in Oxford.

The assault took place at about 2.30am on March 15, in Queen Street.

A man walked past a 25-year-old woman at a kebab van and pulled her hair and touched her inappropriately, police said.

A 25-year-old man who was a friend of the victim was also assaulted by the same man after challenging him over his behaviour.

He sustained cuts and bruises to his arm and leg but did not require hospital treatment.
