British Transport Police have released images of two men they want to speak to about an assault on an inspector at Chorley Railway Station.
The incident happened on Wednesday, August 13, when the revenue inspector asked two men to show their tickets.
PC Allan Fernie said: “They made a show of searching their pockets before showing out-of-date tickets.
“When challenged, one of the men pushed the inspector out of the way and the pair left the station.”
The police said the inspector followed the men, and one of them turned and ran towards him shouting threats.
Fearing for his safety, the inspector backed off.
The men left, shouting further threats at their victim as they went, the police said.
PC Fernie continued: “Thankfully, the member of staff was uninjured, but he was shaken by this incident.
“Nobody who works or travels on the rail network should have to fear violence.
“We are following several lines of enquiry into this incident and, as part of our investigation, are issuing two images.
“I believe the men in these pictures have information about this incident. Who are they? If you know, please contact BTP.”
Anyone who can help is asked to call 0800 405040, or text 61016, quoting reference PSUB/B5 of 12/09/2014.
