Investigators have released CCTV of three men they would like to speak to in connection with the incident, which happened at 10.45pm on Friday, 4 May.
Detective Constable Jason Schweiger, the investigating officer wrote:The 28-year-old victim from Gravesend was standing with his friends close to the bike racks at the Rathmore Road side of the station when he and his group were approached by three men.
Moments later, one of the trio suddenly became violent towards the group and head butted one of the victim’s friends.
In a bid to diffuse the situation the victim tried to pull the pair apart, but was hit on the back of the head with a glass bottle. He was left bleeding heavily and requiring medical attention.
From viewing CCTV, we know that the group had entered the station from the direction of the town centre.
Having spoken to witnesses, I am now keen to trace and speak to the men in these images in connection with the incident. The images aren't clear, but the men pictured are wearing distinct clothing which I hope someone will recognise.
I believe they will have information which can assist the investigation.
Anyone who knows the identity of the men, or their current whereabouts, is urged to contact British Transport Police on Freefone 0800 40 50 40, quoting B6/LS of 12/7/2012 or the independent charity Crimestoppers on 0800 555 111.
