Four juvenile boys were arrested in connection with vandalism at the vacant Mary P. Hinsdale School in Winsted, police said on Wednesday.
All four boys, who are between 13 and 15 years old, were charged with second-degree criminal mischief. All but one were charged with third-degree criminal trespass as well.
Police said the boys entered the building on Nov. 4 and damaged nine windows and one glass door. The damage is estimated at 4,000 and the owners of the building will seek restitution, police said.
The school has been vacant since the summer of 2016.
The boys are scheduled to appear in Superior Court for Juvenile Matters in Torrington on Nov. 30.
