Police have released CCTV images of four men they want to identify in connection with a witness intimidation investigation in Leeds.
A 31-year-old man, who is the victim in an ongoing assault case, was approached by the men in Briggate on a number of occasions between August 28 and September 16.
Detective Constable Lee Thimm, of Leeds District CID, said: "These men have threatened and intimidated the victim in an effort to get the charges dropped in the ongoing case but the victim has refused and the case is continuing. Attempts to interfere with the course of justice willl always be treated very seriously and we would like to hear from anyone who recognises these men or who has any information that could assist the investigation."
Anyone with information is asked to contact DC 908 Thimm at Elland Road via 101 quoting crime number 13160414466 or call the independent charity Crimestoppers anonymously on 0800 555 111.
