A spokesperson for the force said: “At midnight on Saturday 4 December two men waiting at the taxi rank outside the station were approached by another man.
“They engaged in a very short conversation before he punched both men in the face and walked away.
“The victims suffered injuries including broken teeth and a broken nose.
“Officers believe the man in the CCTV images may have information which could help their investigation.”
