CCTV images have been released in connection with an assault at Gloucester railway station in March.

British Transport Police are appealing for the public’s help in tracing a man and a woman they would like to speak to about the incident.

Investigating officer PC Frank Hedley said shortly before 6.45pm on Saturday, March 23 a 39-year-old man from Oldbury in the West Midlands was returning from a rugby match in Gloucester.

“He was in the waiting room on platform four at Gloucester rail station when he struck up a conversation with another man,” he said. “This man disagreed with some of the victim’s comments and approached the victim before headbutting him in the face.

“The victim got up and followed the man out of the waiting room and was further assaulted by the man who then boarded the 6.45pm service to Nottingham via Birmingham New Street.”

He added officers have so far been unable to trace the attacker and are appealing for anyone who knows the identity of the man in the photographs to contact them.

“I’d also like to speak to the woman in these images as I believe she was in company with the man we would like to speak to and, again, I believe she will have information which can help,” he said.

Anyone with information is asked to call British Transport Police on 0800 40 50 40 quoting incident reference B6/WWA of May 5 2013.
