Do you know these men? Officers from British Transport Police (BTP) are appealing for the public's help to identify three men they want to speak to in connection with an incident which took place at Exeter St David's railway station.
Officers have released CCTV images of the men who they believe will have information which can assist the investigation into the incident which took place at about 4am on Monday, 29 July 2013.
Investigating officer, PC Darran Blackwell, said: "Members of rail staff at Exeter St David's station encountered three men at the ticket barriers who had no tickets but wanted to travel on a train to Newton Abbot.
"Rail staff told the men they needed to buy tickets if they wished to travel but they refused and then became verbally abusive towards the members of staff.
"Enquiries have been ongoing to find those responsible and I am now releasing this image in the hope that someone will be able to identify those pictured so that we can speak to them about this incident.
"I would ask anyone with any information to contact BTP straight away."
Anyone who can assist is asked to call British Transport Police on Freefone 0800 40 50 40, or text 61016. You can also call the independent charity Crimestoppers on 0800 555 111.
In all calls, please quote incident reference B8/WWA of 29/08/2013.
