Police want to speak to these two men in connection with a flashing incident on a train between Sheffield and Stockport.
Police said a group of around 10 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.
“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.
“This was an outrageous offence, which has no place on the railways – or anywhere else.”
Now 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.
n Anyone with information is asked to call British Transport Police on 0800 40 50 40 or ring Crimestoppers on 0800 555 111 and quote PSUB/B4 of July 26.
