Police are appealing for witnesses following a serious assault last Thursday morning around 02.55 in the Sleigh Drive area of the city.
A 35-year-old man and his 42-year-old wife were walking their dog near to the roundabout at the junction with Restalrig Road South when a group of youths approached and struck him to the face.
The suspects all then made off from the area and the couple contacted police.
After attending at hospital earlier this week, the victim was found to have sustained serious injuries to his face.
Officers are now urging anyone who can assist with their enquiries to come forward.
Detective Constable John McShane said: “This appears to be a random and unprovoked attack, which has left the victim with some painful injuries to his face.
“Anyone who remembers seeing anything suspicious in Sleigh Drive in the early hours of last Thursday morning is asked to contact police immediately.
“We believe there were a number of other pedestrians and motorists in the area at the time of the assault and are keen to trace these individuals as soon as possible.
“In addition, anyone who can help us identify and trace the suspects is asked to get in touch.”
Those with information can contact Police Scotland on 101 or alternatively, the charity Crimestoppers on 0800 555 111.
