British Transport Police have released CCTV images of the people they want to speak to in connection with the shocking incident at Grays Railway Station at 7.40pm on September 8.

A police spokesman said: "A woman had an altercation with another customer at Grays station. A member of rail staff intervened, however he was also assaulted by the unknown woman.

"The unknown woman was with a man, and they both left the station together. However, at 10.40pm the same man returned to the station, with two other men.

"The member of rail staff was in the safety of the ticket office, where the three men begin to threaten him with violence. They took concerted efforts to smash the ticket window and attempt to kick the door open.
