Taxi driver Christopher Halliwell denies Sian O'Callaghan murder

A taxi driver has denied the murder of Sian O'Callaghan who went missing after visiting a nightclub in Swindon.

Christopher Halliwell, 48, of Ashbury Avenue, was arrested after Miss O'Callaghan visited Suju in Old Town in March 2011.

The disappearance of the 22-year-old office worker led to a search in Savernake Forest after she was reported missing by her boyfriend.

Her body was later found near the Uffington White Horse in Oxfordshire.
