Police are unable to explain why a group of officers caused tailbacks by searching the embankment alongside the A90 near Dundee.
Several police officers were spotted combing the area next to the busy dual-carriageway near Invergowrie just before 3pm today.
Witnesses say they were seen checking the land on both sides of the road.
They were accompanied by a slow crawling police van, which held up traffic on the busy route between the City of Discovery and Perth.
A police spokeswoman told the Tele: “There’s been nothing highlighted to ourselves about this.”
