Melanie Hall murder police release Wiltshire man

Miss Hall went missing in June 1996

Police investigating the murder of a woman whose remains were found on the M5 have bailed a 39-year-old man.

Melanie Hall, 25, from Wiltshire, was working as a clerical officer at the Royal United Hospital in Bath when she went missing 14 years ago.

Officers said the man, from Wiltshire, went voluntarily to a police station on Tuesday afternoon.

He had been held for about 22 hours at an unnamed police station in the Avon and Somerset force area.

Miss Hall vanished after a night out at Cadillac's nightclub in Bath.

Her remains were discovered on a slip road at Junction 14 of the M5 in South Gloucestershire in October 2009.

On 1 July this year, a 38-year-old Bath man was arrested on suspicion of Miss Hall's murder and disappearance. He was later released on bail.
