Police are trying to piece together how a car ended up being submerged in the River Tay.
The discovery of the red vehicle in the water, near the Friarton Bridge, yesterday sparked full-scale emergency response.
The Renault car was spotted by a worker at the nearby sewage plant who feared that there may have been someone trapped inside or elsewhere in the water however this turned out to not be the case.
A Coastguard helicopter was flown-in to assist with the operation.
Two other coastguard teams were drafted in, along with a Broughty Ferry lifeboat crew, police, specialist firefighters as well as crews from Dundee and an ambulance specialist operations response team (SORT).
It’s believed there was no criminality involved in the incident and officers are still working on their inquiries.
A spokesman for Police Scotland said: “We’re satisfied that there was no-one in the car.
“The registered keeper has been traced, and has confirmed the car is not stolen.
“Inquiries into exactly how and when the car ended in the Tay are ongoing.”
