A man has been arrested on suspicion of the murder of a university graduate whose remains were found near a motorway four years ago.
The 44-year-old was arrested at his home last week as part of the investigation into the death of 25-year-old Melanie Hall.
Miss Hall, who worked at the Royal United Hospital in Bath, vanished after a night out at Cadillacs nightclub in Walcot Street, Bath, in June 1996.
On October 5, 2009, human remains were found by the side of the M5 by a workman who was clearing vegetation on the slip road at junction 14, near Thornbury, south Gloucestershire.
Two days later, the remains were identified as those of Miss Hall, from Wiltshire.
