A man has been taken to hospital after he was the victim of a "nasty assault" in Aberdeen.
The 30-year-old, who suffered facial injuries, was taken to hospital by ambulance after being attacked by two men on Justice Street at about 12.45 pm on Thursday
Grampian Police officers cordoned off the area for enquiries to be carried out and the force is now appealing for witnesses.
Constable John Richardson of the Mobile Support Unit who is dealing with the incident said: "We are still trying to establish the full facts but I believe that a number of people would have seen what happened.
"This was a particularly nasty assault and I am appealing for anyone who can assist our investigation to contact us as soon as possible.
"Officers have been carrying out house-to-house enquiries in the area and we are especially keen to hear from anyone who may have seen a group of individuals fighting or heard a disturbance in the area at the time to contact us.
"If anyone saw anything that might be linked to this incident or if they have heard something about it, please contact the police and share that information with us."
Officers said they were keen to identify a man with short brown hair, aged around 25, who was wearing a light brown shirt or a distinctive grey tracksuit top with three stripes across the right shoulder. He was also wearing blue jeans.
The second man is described as having dark hair, aged around 45, and was wearing blue jeans and a black or blue jacket. The men were last seen heading towards the Castlegate from Justice Street.
