We’d like to speak to this man in connection with an assault at Burger King in Marylebone station.

On Thursday 9 March at around 9.20pm, a man became agitated after jumping the Burger King queue and being told he would have to pay for a drink if he wanted a cup.

He refused to pay and then went behind the counter where he approached a member of staff and punched him twice in the head.

He then threw the victim onto the floor and tried to stamp on him, before leaving the scene.

The victim, a 41-year-old man, sustained grazes to his leg and bruising around his eye.

Investigating officer, Det Con Martin Coburn, said: “I would like to speak to the man shown in the CCTV image as he may have information which could help with the investigation.

“This was a violent attack against a member of staff who was simply doing his job and it is vital that we find the person responsible. Fortunately, the victim has recovered from his physically injuries, which in the end were not serious, but they could have been a lot worse as the offender was trying to stamp on the victim whilst he was on the floor.

“If you have any information about what happened or recognise the man shown in the CCTV image, please contact me by calling 0800 40 50 40 or text 61016, quoting reference number 211 13/04/2017.”
