A 66-year-old man is in a serious condition in hospital after being struck by a car in Aberdeen.
The incident happened around 2.30pm on Monday on Powis Terrace at the junction with Bedford Road next to the traffic lights.
The pensioner was hit by a grey Lexus IS car, registration number SC06 XEL, which failed to stop, police said.
Passers-by went to the aid of the man and he was taken to Aberdeen Royal Infirmary by ambulance where he remains in a serious condition with leg and chest injuries.
Officers are appealing to witnesses who may have seen what happened.
The vehicle carried on towards the St Machar area and was also seen a short time later in the Ashill Drive area of Aberdeen where it was abandoned. Four men were seen leaving the vehicle.
It has been recovered by police and inquiries are ongoing to trace the driver and occupants.
Road policing inspector Steve Manson, said: “It appears that the Lexus was being driven erratically prior to the incident and after being involved in the collision with the pedestrian it failed to stop.
“The pedestrian suffered serious injuries and the driver made no attempt to stop and check on him.
“We are appealing for anyone who saw the collision, or saw the Lexus before or after the incident, to get in touch. In particular, if you have dash-cam footage that can assist our enquiries then please contact us.
“Those who can help should contact Police Scotland on 101 or make a call anonymously to the charity Crimestoppers on 0800 555 111.”
