A CCTV image has been released by detectives investigating the assault of rail staffer by a fare dodger.
At around 3.30pm on 9 October, a member of rail staff working on a train between West Worthing and Worthing railway station encountered a man travelling without a ticket.
The man without a ticket began to speak aggressively to the member of staff, before attacking him, throwing a closed can at him and damaging his glasses.
Officers believe the man in the image may have information which could help with their investigation.
