Police want to speak to these men in connection with a flashing incident on a train between Stockport and Sheffield.
British Transport Police have released CCTV stills of two men they want to speak to following the incident which happened between 7.55pm and 8.35pm on Saturday, July 19.
Police said a group of around ten men got onto the East Midlands Liverpool to Norwich service at Stockport and began to behave in a ‘disorderly manner’.
PC Matthew Peters said: “At some point during the journey two of the men exposed themselves causing other rail passengers extreme discomfort and distress.”
He added: “I believe the men are from the Alfreton and Nottingham areas and I am confident the two men pictured have vital information about what happened.
“If you recognise them, or have any other information about the incident, please call us.
“This was a outrageous offence which has no place on the railway – or anywhere else.”
To help please call British Transport Police on 0800 40 50 40 or ring Crimestoppers, anonymously, on 0800 555 111.
