Police said four youths were seen damaging the building

Vandals have broken over 50 windows on a Grade II listed conservatory in a park in Lancashire, police have said.

Four youths were seen damaging the building in Corporation Park, Blackburn, at about 21:15 BST on Wednesday.

The damage to the conservatory, which was built in 1900, could cost tens of thousands of pounds to repair.

Sgt Conrad Tapp from Lancashire Police appealed for witnesses to the “mindless criminal damage”.
