Police are appealing for possible witnesses pictured in new CCTV footage to come forward in relation to the alleged serious sexual assault of a 22-year-old deaf woman in Lincoln in 2010.

In October last year Lincolnshire police released the below picture of a man who may have been in the area at the time of the incident, which took place at the back of Sippers pub in Broadgate, Lincoln, between 1.30am and 3am on December 18, 2010. This man has still not been identified.
