The Tucson Police Officers Association gave Amphitheater Public School district a $3,000 check today.
This comes after three teenage boys were arrested for vandalizing four schools in the district. The boys are accused of breaking windows and setting a fire in the library.
School officials say they had to temporarily shut down the library because of smoke damage.
The 12-year-old, 13-year-old, and 15-year-old suspects are facing charges of burglary, aggravated criminal damage, and arson.
