Police in Edinburgh are appealing for witnesses following a hit and run collision on the City Bypass.
The incident happened around 2.55pm on Friday 22nd June on the eastbound carriageway and the Calder junction off-slip.
A blue or silver car has struck the rear of a white Kia Venga, resulting in the vehicle striking a blue Audi A3.
Three other vehicles have then attempted to take evasive action, but also become involved in a separate collision with each other.
The car responsible for the initial collision failed to stop and inquiries are ongoing to trace the driver.
Road Policing Officers responded to the scene and closed Lane 2 for an hour and a half while they conducted inquiries.
Anyone with information is asked to come forward.
Constable Grant Hastie from the Road Policing Unit in Edinburgh said: "Thankfully no one was seriously hurt during this incident, with only minor injuries being reported by the driver of the Kia.
"Not only will the driver of the blue or silver car have sustained damage to their own vehicle, but they would also have seen the consequences of the subsequent collisions, yet they still failed to stop.
"We are keen to hear from any road users who were on the Bypass on Friday afternoon and witnessed what happened, or who can help us identify the driver who made off.
"If you have any information that can assist with our ongoing inquiries then please contact police immediately."
Those with information can contact the Road Policing Unit in Edinburgh via 101 and quote incident number 2292 of the 22nd June. Alternatively, an anonymous report can be made to the charity Crimestoppers on 0800 555 111.
