Vandals cause £18,000 of damage at Midlothian schools
One school targeted in Bonnyrigg had 122 broken windows in just one day.
Vandals have caused £18,000 worth of damage to two primary schools in the same town.
At one school, they smashed 122 windows in one day.
The schools targeted in recent weeks were Hawthornden and St Mary's primaries in Bonnyrigg, Midlothian, police said.
At Hawthornden alone, 80 skylights and 42 double-glazed windows were shattered on April 7.
Police Scotland and officials at Midlothian Council have assessed the total repair bill for all the damage as being £18,000.
Appealing for information, Inspector John Dryden said: "This is an appalling attack on the primary school and the cost of the repair will ultimately come from Midlothian Council's budget - money that would be better used for vital services to the community.
"It would have taken a significant period of time for the vandals to smash 122 windows and the noise alone must have attracted attention.
"I would also ask parents and guardians to assist in preventing further incidents by ensuring they know where their children are and what they are doing when out and about."
Midlothian Council said it has carried out a clean-up operation to make sure none of the pupils or staff are injured by the broken glass when they get back from the Easter break.
But until the staff return, they will not have the chance to assess the damage to resources inside the school that may have been contaminated with debris.
A spokesman for the local authority said: "It is not just the financial cost to the council, but the emotional cost to our school community."
Anyone with information is asked to contact police on 101.
