The hunt is on to find a thug who pushed a worker at Willesden Junction train station to the floor and punched him four times in his face.

Detectives have today released the image of a suspect they would like to speak to in connection with the brutal attack on July 4 at 6.40pm

The 49-year-old victim sustained some swelling and bruising to his eye.

The suspect had got off an Overground train service from Stratford before he made his way to the ticket barriers and provoked an argument with his victim before he attacked him.

PC Katie Lockwood, investigating officer, said: “This was a violent, unprovoked and nasty assault and we are determined to trace the person responsible.

“No one should ever be treated like this and we will always look to take firm action against those who assault, intimidate or harass passengers and rail staff.

“As part of my enquiries British Transport Police have seized CCTV and spoken with witnesses. However, we are keen to speak with anyone else who may have witnessed this assault or recognise the man in the CCTV images.”
