An Indian man who came to the aid of a woman seen arguing with two men in the street, had his jaw broken in a racist assault, police have said.
The 21-year-old was walking with a friend on Edinburgh's Waverly Bridge in the early hours of Saturday when the attack happened.
He was punched by one of the men before the second struck him on the head, knocking him to the ground.
Lothian Police described the attack as "an appalling assault".
They said that after the victim intervened on the woman's behalf, three other men became involved in the dispute.
After being struck and knocked to the ground, all five men and the woman left the man and ran off towards Princes Street.
The victim was taken to St John's Hospital in Livingtson where he was found to have broken jaw.
A police spokesman said: "This has been an appalling assault levied against the victim for no reason other than his race and his efforts to come to a young woman's assistance."
