Another victim who is believed to have been killed by the murderer of missing nightclubber Sian O'Callaghan went missing "several years ago", detectives have revealed.

Police said they had launched a painstaking search at a new location near Northleach, in Gloucestershire, after confirming Miss O'Callaghan's body has been recovered from an area near the village of Uffington, 15 miles east of Swindon.

Steve Fulcher, who is leading the double murder inquiry for Wiltshire Police, said there was "only one" outstanding missing person on the force's records.
