A THUG attacked a station worker after refusing to buy a train ticket.

Police probing the incident have now released CCTV images of the man they are looking for.

The incident happened at Grays railway station, in Station Approach, at 12.55pm on Monday September 6.

The man pushed his way through two barriers on Southend-bound platform two, when he was confronted by the male station worker.

But the attacker shoved him in the chest and started threatening him, before crossing the tracks and running to a level crossing, fleeing the station.
