DETECTIVES are this morning still searching the Oxfordshire countryside for a second body after finding that of missing Sian O'Callaghan last night.

Roadblocks are still in place on the B4507 near the White Horse at Uffington.

A 47-year-old man is still being held by police on suspicion of two murders including that of the missing 22-year-old Swindon nightclubber.

Police, who have been searching a remote spot near Kingston Lisle yesterday found Miss O'Callaghan's body and say they know the location of the second victim.

Det Supt Steve Fulcher said the arrested man - named locally as taxi driver Christopher Halliwell - had told them the locations of both bodies.

Wiltshire Police are due to release more details of the case this morning.
