A CITY centre sex attacker is being hunted by police.

A 40-year-old woman suffered a serious sexual assault behind a pub in Westgate early on Monday, detectives revealed today.

The woman had been approached by a man close to the pub and she was attacked after they walked to the back of the premises.

The suspect was described as Asian, in his early 20s and about 5ft 10ins tall. He had longish black hair and was wearing a light grey hooded top, a black or dark blue hat with flaps on the side and dark grey tracksuit bottoms.

Detective Superintendent Simon Atkinson, of Protective Services (Crime), said: "This must have been a harrowing ordeal for the victim, who is now being supported by specially trained officers.

"We would appeal for anyone who saw anything suspicious in the Westgate area, either before or shortly after the incident to contact the police with any information they may have.

"We would also like to speak to two men who we believe were seen with the suspect that evening.

"Both men are believed to be Asian and in their late teens or early 20s. One was of quite stocky build, wearing a hat, a grey hooded top, grey tracksuit bottoms and dark blue trainers.

"The second man was wearing a blue hooded tracksuit top, which was made out of shiny material, tracksuit bottoms and dark trainers. He was riding a blue or silver mountain bike."

Anyone with information is asked to contact police on 101 or Crimestoppers on 0800 555 111.
