A SEX attacker with chubby cheeks knocked on a young woman’s door and assaulted her.

The victim, who is in her 20s, had just got back to her East Oxford home when she was attacked at about 1.45am this morning.

Police say a man asked for a glass of water at the house before trying to kiss the woman and sexually assaulting her. The victim screamed and the man ran off.

Police described the suspect as Thai, Indian or possibly mixed race. They said he was in his late 30s or early 40s, about 5ft 4ins, of a stocky build, with chubby cheeks and stubble.

He was wearing a black leather jacket over a yellow hooded top.

Police are today speaking to residents and running reassurance patrols.

Det Insp John Turner, investigating officer, said: “This was a very nasty attack on a woman in her home, which has left her badly shocked. Thankfully this kind of attack is very rare in Oxford. We are doing everything to locate this man.”

He added: "We would urge anyone who was in the area at that time, or on Cowley Road at that time and can identify the man from the description then we would urge them to please call 101 as a matter of urgency."
