Police say a major search of the River Tay involving rescue helicopters and the RNLI was a false alarm.
Emergency services were called to the watercourse in Perth after a worried member of the public raised the alarm while driving over the South Street bridge at about 4.15pm on Wednesday.
A multi-agency response was scrambled following the report, with police joined by firefighters, the Scottish Ambulance Service and the UK Coastguard.
Coastguard helicopters were sent from Prestwick and Inverness bases along with rescue teams from St Andrews, Carnoustie and South Queensferry were deployed.
The Broughty Ferry RNLI lifeboat also attended.
The search focused on a stretch of the Tay between West Bridge Street south towards the rail crossing over Moncreiffe Island.
The emergency services were stood down at about 9.20pm, with police satisfied no-one had entered the water.
On Thursday morning a Tayside Police Division statement was issued which read: “Regarding the incident at the River Tay in Perth yesterday evening, after an extensive search of the area nothing was found, and we are content this was a false alarm with good intent.
“Thank you to everyone in the area for your patience and understanding while we conducted our inquiries.”
