Vandals struck Lincoln High School over the weekend, shoving glue and crazy glue into door locks.
Authorities told FOX40 that school employees discovered the vandalized locks Monday morning. It took some time to get the doors open.
Wednesday is the last day of school.
A $1,000 reward for information is being offered.
Surveillance footage caught the vandalism on tape. Andria Borba will present you that video; make sure to watch FOX40 News at 5:30.
