CCTV cameras have captured the moment a rail staff member was almost pushed onto the tracks at Newport train station.
The incident happened on the 13th of August at around 8.40pm.
A man had been seen holding doors of a train open as it was preparing to leave.
Staff asked the man to stand clear but soon after the train left the station, the man ran at the member of staff - pushing him.
The British Transport Police is now calling on the public to help identify the man in the CCTV image to help with their enquiries.
