Police in Falkirk are on the hunt for the driver of a Land Rover Discovery seen acting suspiciously in Denny last weekend.
Officers were alerted to reports the driver was bearing high visibility markings and flashing lights on the A872 Stirling to Denny road and on Nethermains Road in Denny at around 5:40pm on Sunday June, 20.
