A man was seriously injured after being struck by a taxi in a hit-and-run.
The incident happened on Princes Street in Edinburgh city centre at 4.20pm on Saturday.
A 41-year-old man was hit by a black cab across from Next which then failed to stop and drove off.
He suffered a serious ankle injury and was taken to hospital before being released.
Sergeant Fraser Wood: "This incident resulted in the taxi's nearside wing-mirror being broken off and so it is highly unlikely that the driver would be unaware they were involved in a collision.
"We are keen to hear from members of the public who were on Princes Street at the time and witnessed what happened, or who can help us identify the person driving the taxi.
"In addition, anyone with any further information relevant to this investigation is urged to contact police immediately."
Anyone with information is asked to contact 101.
A petition calling for Erewash cabbies to be allowed to have fully-tinted windows in their taxis has been rejected over fears that vehicles could be used to enable the abuse of vulnerable children and adults.
