A man has been left with a fractured cheekbone after he stepped in to stop his attacker shouting at others at a bus stop.
The 66-year-old man and his wife were waiting at the temporary bus stop on the Western Approach road in Edinburgh at around 9.55pm on Friday August 3 along with several other people.
A man walked up to the group and started shouting at them. The victim stepped in to stop the abuse and had racial slurs shouted at him before he was punched in the face.
A bus arrived and the victim and wife got on. A few days later he went to hospital and doctors discovered he had a fractured cheekbone. Police were then called.
Officers would like to speak to two elderly women who got on the double-decker bus at the same time as the victim and had witnessed the assault.
The attacker is described as white, in his mid-20s, around 5ft 10ins tall and was wearing a white shell suit top, light coloured bottoms and white trainers.
Detective Sergeant Dave Pinkney said: "The victim, who is English, stepped in to prevent other people at the bus stop being harassed by the suspect and has suffered a painful injury to his face as a result.
"We are now keen to speak with anyone who was in the queue at the time and remembers seeing this confrontation.
"Similarly, anyone with any other information that can assist with our enquiries, or who can help us identify the male responsible is asked to contact police immediately."
Anyone with any information can contact Lothian and Borders Police on 0131 311 3131 or through Crimestoppers on 0800 555 111.
