Today we're releasing a CCTV image after two members of train staff were attacked at Cleethorpes station, North East Lincolnshire.
The incident happened at 6.45pm on Saturday 21 December.
Two men are reported to have become aggressive and grabbed a train driver. They then grabbed a conductor when he intervened.
Officers would like to speak to the men in the images who may have information that can help their investigation.
Anyone who knows them is asked to contact BTP by texting 61016 or by calling 0800 40 50 40 quoting reference 417 of 21/12/19.
Alternatively, call Crimestoppers anonymously on 0800 555 111.
