Officers from the British Transport Police who are investigating a serious assault on-board a London Underground service on an NHS worker, have released an image in connection with their enquiries.
At around 10 pm on Saturday 3 October, an NHS worker was travelling on a London Underground Circle line service when he noticed a group of two men and one woman on-board not wearing face coverings.
The man approached the group and challenged them on why they were travelling without face coverings on.
This encounter then led to an argument between the man and the group.
One of the men from the group then punched the victim several times in the side of the head.
The attacker then threw him off the train onto the platform at High Street Kensington station.
The group stayed on the service as it left the station.
The victim, who works in the NHS, suffered serious injuries, including a chipped jaw and three breaks to his eye socket.
Officers believe the man in the image may have information which could assist their investigation.
