A man who has breached his prison release licence could be in Twickenham or Mortlake.
Police are looking for Samuel Gordon, 26, who is wanted on recall to prison for not attending appointments with the probation service.
He was last seen in the Twickenham area in early June.
Gordon had received a two-year prison sentence in July 2013 for supplying cocaine.
Police believe Gordon is still in Richmond as he was visiting family in June.
He is white, 6ft 2in, has brown straight hair, hazel eyes and has a tattoo of a cannon on his left hand.
Members of public are advised not to approach him and to call police immediately on 999.
Anyone with other information should call Richmond Wanted Offender Unit on 020 8247 7191 or call Crimestoppers anonymously on 0800 555 111.
