Police have released CCTV images of a man they want to speak to about a serious sexual assault in Leicester city centre. It happened between 3.15am and 3.35am on Friday, February 1 in an alleyway off West Street. The 29-year-old female victim spoke to a man in Kent Street before they both walked across the city to Regents Road and West Street. As they walked into the alleyway the woman was assaulted and her brown Louis Vuitton bag was taken. A 19-year-old man has been arrested in connection with the incident and released on police bail pending further inquiries. Officers have already appealed for information once, and now they have issued a further appeal and have released the CCTV images. The man in the CCTV images is wearing a Gio Goi black and yellow hooded top with green or yellow writing across the front. The bike is a white and red men's mountain bike. Detective Sergeant Mark Sinski said: "We would urge him or anyone who recognises him to get in touch with police. We are also keen to speak to anyone who may have found discarded in the area a brown Louis Vuitton handbag or its contents which included an FCUK make up roll, purple purse and brown Specsavers glasses with gold swirls on the joints. Anyone with information is asked to contact DS Sinski on 101 or Crimestoppers anonymously on 0800 555111.
