Nine council vehicles were damaged in a vandal attack at South Lanarkshire Council’s Lanark headquarters over the Christmas holiday period.
The total cost of the damage is estimated at around £16,000.
The vandalism took place between Friday, December 23, and Wednesday, January 4, in the car park at the South Vennel offices.
“The damage caused is significant,” said police community officer James Higgins.
“Inquiries are ongoing to trace those responsible.
“Anyone with information on those responsible is urged to call Police Scotland on 101.”
The council’s head of fleet and environmental services, Shirley Clelland, said: “We are appalled at this vandalism of council vehicles.
“There were a total of nine vehicles damaged, including council pool cars and small vans.
“The damage is still being assessed in terms of the cost to carry out repairs.
“We would urge anyone with any information to contact the police.”
