One man, who is described as white, around 50 years old and 6ft tall, can be clearly seen pushing the security guard, before turning and going in a different direction. The injured security guard was knocked unconscious, and taken by the London Ambulance Service to hospital where he was treated for concussion and released later that day.

Detective Chief Inspector Andy Barnes, from the Public Order Investigating Team, said: "I am appealing for information to trace the man seen in the footage we have released today. Someone will recognise him and I am asking them to come forward. The footage shows the level of violence used, which is unacceptable."
The man had a partly shaved head and a receding hairline. He was wearing black leather trousers and a black leather motorcycle jacket with a light brown stripe on the arms.
