Authorities say the students used industrial-strength glue on all the classroom doors at Royal High School late Tuesday. Maintenance crews worked most of Wednesday to clean the glue out of the locks.
Police were able to identify the culprits through surveillance video and other evidence. Michael Clear, assistant superintendent for the Simi Valley Unified School District, said both seniors were suspended for the rest of the academic year and would not be allowed to attend commencement ceremonies next week.
"This was not a harmless prank. It can get very expensive, and not only that, it's wrong," Clear said.
A damage estimate was not immediately known because officials were not yet sure if the locks would need to be replaced.
