Officers are seeking the public’s help in finding a man sought in connection with a violent attack on a member of rail staff.

At about 7.25pm on 2 September, a man urinated on the entrance gates of Piccadilly Underground station after finding the toilets closed.

When a male member of staff then refused him travel, the man became violent and threatened him. He then lunged towards the victim and bit the right side of his face.

Investigating officer PC Matthew Hogg said: “This was a nasty and unprovoked attack on a person who was just doing their job.

“We will not stand for it. If you have any information or recognise the man in this photo, please let us know.”

Anyone with information is asked to contact British Transport Police on 0800 40 50 40 or text 61016, quoting 500 of 2/9.
