Mystery still surrounds the events which led to a woman being found injured on a Perthshire bridge during the early hours of Tuesday.
The woman was discovered at around 1.30am on Dunkeld Bridge by a member of the public before she was taken to Ninewells Hospital, Dundee.
It is understood officers have still not been able to speak to the woman, who is thought to have been seriously injured in the incident.
Yesterday afternoon a force spokesperson said inquiries were “still ongoing”.
Police remained at the scene for more than 13 hours as they tried to establish the circumstances that led to the woman’s injuries.

One onlooker said: “It did look serious when we drove past in the work van.
“There was a lot of police activity on the bridge. Not sure if a car crashed, but at least three police cars and an incident van were there.
“I was driving into Dunkeld. The left-hand part of the bridge was partially closed to pedestrians.”
A Police Scotland spokesperson said: “We received a report of a woman found with injuries at Dunkeld Bridge at around 1.30am on Tuesday.
“She was taken to hospital for treatment and inquiries remain ongoing.”
