An urgent appeal for help has gone out after CCTV footage was found of three men suspected of a station attack five months ago.

British Transport Police hope people can help their investigations into the attack on the man on September 24 in Eynsford station car park.

The 20-year-old victim was attacked after getting off the 9.42pm service from Blackfriars.

The three men walked into his carriage between Swanley and Eysnford, then followed him off the train.

"When he got off, he walked past the men who then followed him into the station car park and demanded he handed over his belongings," said DC Devereese.

He gave them his mobile phone, iPod and wallet. They also took his watch.

"Once all the property was handed over he was set upon by the three who kicked and punched him in the face, head and upper body."

The men may have left Eynsford on a 10.45pm service to London.

The violent attack left him with cuts, bruises, and intimidated.
