Emergency services are set to descend on the River Tay for a training exercise to test their response to a major incident.
Folk are being urged not to panic if they spot, what looks like a body, in the river tomorrow.
Emergency services are set to descend on the river for a training exercise to test their response to a major incident.
Two boats will be placed in the water, near Perth, to simulate a crash.
Dummies will also be in the water between Moncreiffe Island and Newburgh and actors will be placed on the shore adding to the exercise.
Police have moved to pre-warn locals with emergency workers from nearly all services attending along with Dundee Airport Fire Service and NHS Tayside staff in attendance.
Perth and Kinross Council, British Red Cross, Willowgate Activity Centre and Perth Sailing Club will also be participating.
Exercise Director Ross Greenhill, from HM Coastguard, said: “We always say this is training for the day that we hope will never come. It’s difficult to get everyone together for an exercise so this is a rare opportunity to test all the emergency services in a controlled environment without putting the public at risk.
“This makes sure that if a real emergency happens, we are well prepared for the challenges that major incidents can bring.
“People in the area will see a lot of activity and a large emergency services presence so we wanted them not to be alarmed and know what’s going on.”
The exercise will take place around 6pm lasting for about four hours.
