FRESH images released by police show Sara Clark in the hours before the alleged sex attack took place on a recreation ground near her home.

Detectives have taken the unusual step of releasing the pictures in the hope of tracing two men who could have clues about just what happened to the 18-year-old that night.

Sara died having jumped from a motorway bridge three days after she said she had been raped.

She is thought to have been hit by two vehicles.

Her grieving parents said at the time that their daughter had become depressed and may have committed suicide because police did not believe her story.

Howell and Amanda Clark were later informed, during a meeting with detectives, that Sara had been contacted but no message had been left when she failed to answer the phone because of the sensitivity of her allegations.

Closed Six weeks after the alleged rape took place, a fresh appeal to find the two men shown in the footage has been made.

Both men were seen with Sara prior to when she claimed to have been attacked in Testwood Recreation Ground, Salisbury Road, Totton.

The first man was seen walking with the teenager to Southampton Central railway station where they walked on to the platform before leaving again when they realised the train between Southampton and Poole had been cancelled.

They walked to a replacement bus outside the station and that is where the man left Sara, who then boarded the bus.

The second man was also captured on CCTV cameras at the train station and he is known to have boarded the same Wilts and Dorset bus which left the station at 12.42am.

Both got off the double decker vehicle at the same stop, outside the Asda superstore in Totton, a short time later.

He can be clearly seen wearing a pink shirt under a long-length jacket and carrying a shoulder bag.

Det Insp Geoff Crowe said the men were "two key and potentially significant witnesses".

He told the Daily Echo: "It's important that we speak to both these men, in particular the man on the bus or anyone else who may have seen Sara during the evening, or while she walked home from Totton to Calmore."
