No searches are currently taking place along the River Tay following an incident on the road bridge on New Year’s Day.
The force said a man was “seen to jump off” the crossing at about 3.40pm after entering the walkway from the Dundee side. They are appealing for information on the person.
The incident sparked an air and sea search of the River Tay which went on well into the evening, with a coastguard helicopter drafted in to help.
Both the Brought Ferry lifeboats were launched at around 6.30pm after police raised the alarm.
A large area between Monifieth and Tayport was searched.
Police say they are yet to receive reports of a man matching the description of the person.
He was described as white, in his 50s and wearing a dark, “tammy style” hat, a large black winter coat, a dark green jumper or shirt, grey jeans and black shoes.
The UK Coastguard said no searches of the River Tay had taken place on Tuesday.
On Monday a rescue helicopter from Prestwick was called in to aid the search, but it was stood down at 10.40pm.
Coastguard rescue teams from Carnoustie and St Andrews also assisted.
A UK Coastguard spokesman added: “We are not carrying out any searches at this time. We received the call at 6.06pm. The last of our team was stood down last night at 10.40pm.”
He said they would only be back out if “further information” comes to light or if police request assistance.
A Tayside Police Division statement said: “Police Scotland is appealing for information about an incident that happened on the Tay Road Bridge around 3.40pm yesterday (January 1).
“A man was seen to jump off the bridge into the Tay, nearer the Fife end of the bridge. He is described as white, in his 50s, wearing a dark tammy style hat, a large black winter coat over a dark green jumper or shirt, grey jeans, and black shoes.
“He was also seen to be smoking a cigarette he had taken from a tobacco pouch.
“We have not had any persons reported missing to us who match this description at this time, and we need to identify who he is, along with trying to find him. It has been confirmed that he entered the bridge walkway from the Dundee end.
“If you have any information which could help us, please call 101 or speak to any Police officer. Our reference is CR/76/18.”
