A gay man was attacked and died after being subjected to homophobic taunts in Trafalgar Square by a group including a girl from East Sussex, the Old Bailey heard.

Ian Baynham, 62, died from a brain injury 18 days after being being punched to the ground on September 25 last year.

He was confronted by two teenage girls outside South Africa House after they had been drinking, said Brian Altman, prosecuting.

Mr Baynham, who was openly gay, was with his friend Philip Brown and they were called "f****** faggots", it was alleged.

After a confrontation, a youth who was with the girls punched Mr Baynham to the ground, where the females kicked and stamped on him "like a scene from Clockwork Orange", the jury was told.

Joel Alexander, 19, of Thornton Heath, south London, Rachel Burke, 18, of Three Oaks, East Sussex, and Ruby Thomas, 18, of Lichfield, Staffs, deny manslaughter.
