Police appeal for witnesses in MI6 murder case
Scotland Yard has released new CCTV images of Gareth Williams, the MI6 worker whose body was found in a padlocked bag in his London flat.
Detectives say he was unclothed - and a post mortem examination has revealed no trace of alcohol or drugs. The senior investigating officer, Detective Chief Inspector Jacqueline Sebire, has appealed for two potential witnesses to come forward.
