A man subjected staff at Leeds Railway Station to vile racist abuse after trying to get through the barriers without a ticket.
Police are appealing to people in West Yorkshire and have released CCTV of a man they want to speak to in relation to the incident on Tuesday, August 16.
The staff member was racially abused after telling a man he needed a ticket to travel.
The suspect soon returned having bought a ticket, which he threw at the victim after passing through the barriers.
Investigating officer PC Fahd Khan, of British Transport Police, said: “No-one should have to suffer such offensive abuse, particularly when they are just doing their job.
“After reviewing CCTV we have issued an image of a man we want to speak to.”
