A man was left with a broken jaw after a suspected homophobic attack in Edinburgh on Saturday night.
The 24-year-old was walking with friends on Waverley Bridge when they were confronted by three men who shouted abuse at them.
One of them punched the victim, knocking him to the ground, before running off towards Princes Street.
Police described it as a "cowardly and vicious" assault, and urged witnesses to contact them.
A spokesman for Lothian and Borders Police said: "Anyone who was in or around Waverley Bridge about midnight this morning and saw anything suspicious, or who can help identify the suspects, is asked to contact police immediately.
"Lothian and Borders Police will not tolerate hate crime in any form and will robustly deal with anyone found to be responsible."
One of the suspects was described as black, in his early 20s, 5ft 6ins and of medium build. He was wearing a black hooded top, black and yellow scarf and black trousers.
The second man was white, tall, about 21 and slim. He had dark blond hair and was wearing a red top.
A third man was described as white, aged 20 to 25, about 5ft 7ins, of average build and wearing a dark hooded top.
