Vandals have caused thousands of pounds worth of damage to a Caithness school just days after it closed its doors for the final time.
Around 30 windows were smashed at the old Wick High School some time on Tuesday evening.
Police believe the culprits must have loitered for some time to cause that amount of damage and have urged anyone with information to come forward.
The school closed for the final time before the school Easter holidays .
Pupils are finally due to move into the long-delayed new Wick Campus when the school reopens on Wednesday, April 26.
Police said it is impossible to put an exact value on the damage – but said it is estimated “to be in excess of several thousand pounds”.
Inspector Marlene MacDonald said: “This is an example of utterly mindless and wanton vandalism. It is absolutely unacceptable that buildings in our community are targeted in this way.
“Whoever perpetrated this act must have spent a considerable amount of time outside the premises and we would urge anyone who saw anything concerning or suspicious in the area at the time to contact police as soon as possible on 101.
“As well as the monetary value of the damage, the impact on the community cannot be underestimated and I would urge the community to pull together to identify those responsible.
“If anyone has any information which may assist us please get in touch.”
The building is currently being offered for sale by Highland Council as a redevelopment opportunity.
The land is currently allocated as being suitable for mixed use – namely business, community or housing.
It is on the market for offers over £250,000.
A Highland Council spokeswoman said: “We support Police Scotland’s appeal for witnesses following vandalism at Old Wick High and urge anyone with information to contact the police on 101 or Crimestoppers anonymously on 0800 555 111 or use the Crimestoppers online form at crimestoppers-uk.org.”
