A man urinated on the gates of a tube station before sinking his teeth into the face of a worker.

The early morning attack happened after the man was seen urinating on the gates of a Piccadilly Circus tube station.

A Tube worker saw him and refused to let him in the station. He then lunged at the worker, biting the right side of his face.

Police have now released a CCTV image of a man they want to speak to following the attack at around 7.25am on Friday September 2.
