Police have issued a CCTV picture of a man they want to speak to after a Metrolink worker was punched in the jaw at a tram stop.
The staff member was attacked at the Prestwich tram stop in August, police said. He was hit in the face after asking a ticketless passenger to leave.
Officers shared a photo of a man they want to talk to about the incident as part of an appeal on social media. Anyone who recognises him is being urged to get in touch.
