Detectives determined to find a man who carried out a serious sex attack on a deaf woman have made a new appeal for information three years on.

The 22-year-old victim was assaulted behind the Sippers pub, in Broadgate, Lincoln, between 01:30 GMT and 03:00 on 18 December 2010.

Officers have released an image of a man they want to speak to and pictures of two others who might know him.

Nobody has ever been arrested in connection with the attack.

Det Sgt Cunningham said: "We know this took place a long time ago, but these men may still live in the area or visit regularly and we would like anyone who recognises them, or the men themselves, to get in touch as soon as possible."
