Police have made a second arrest over the murder of Bath graduate Melanie Hall 14 years ago, two months after another suspect was released on bail.
A 39-year-old man, from Wiltshire, was detained on suspicion of murder after handing himself in at a police station in the Avon and Somerset area yesterday afternoon.
In July a 38-year-old man was arrested after he voluntarily attended Bath police station. He was later released on bail.
Ms Hall, a psychology graduate, went missing in June 1996 after a night out in Bath. Her remains were discovered hidden in five plastic bags at the side of the M5 motorway last October.
Det Chief Insp Gareth Bevan described the latest arrest as an important step but stressed that the investigation is still ongoing.
