A KEY witness has contacted police investigating the alleged rape of a Hampshire teenager who three days later jumped to her death off a bridge over the M27.

The man came forward following the release of CCTV footage taken at Southampton Central railway station which shows Sara Clark in the hours before the alleged sex attack took place at a recreation ground near her home.

Through the Daily Echo, detectives appealed for two men who were also captured on CCTV on May 30 at around 12.40am to come forward in the hope they could provide vital clues.

Following last week's appeal one of the men who got on the same Wilts and Dorset bus from the railway station that Sara used has contacted the police and given a witness statement.

Sara, 18, from Calmore, Totton, fell on to the M27 westbound carriageway underneath the Hill Street Bridge at around 3.50am on June 2. Her body was found between junctions two and three.

Her parents Howell and Amanda Clark believe that their daughter may have committed suicide because she felt police did not believe her story that she had been raped three days earlier at Testwood Recreation Ground, Salisbury Road, Totton.

Police are also appealing for another man who was seen walking with the former Testwood School pupil to Southampton Central railway station where they went on to the platform before leaving again when they realised the train between Southampton and Poole had been cancelled.

They were filmed walking to a replacement bus which was waiting outside and that is where the man left Sara, who then boarded the bus.

Police have renewed their appeal for him or anyone who knows him to get in touch. Anyone with information should phone the Operation Roland team on 0845 045 4545 or Crimestoppers anonymously on 0800 555 111.

A separate investigation is being conducted into the circumstances leading to Sara's death by the Independent Police Complaints Commission.
