DENVER — Police say two juveniles believed to have been armed with long rifles and carrying backpacks are in custody after school employees spotted them inside an empty school building late Monday.
Just after 9:00 p.m. a burglar alarm went off from Greenwood Elementary. When officers arrived on scene they discovered a broken window.
About an hour later two school employees reported to police they saw two people entering Noel Middle School carrying rifles and backpacks. Police surrounded the school and a bomb squad was called to the scene. A telephone notification was sent to neighborhood residents warning them to stay indoors.
Surveillance footage captured the suspects each carrying a long rifle and backpacks. Police tried to use the school's public address system to try to communicate with them.
Denver Police Chief Robert White said when the two suspects were apprehended neither was in possession of the rifles nor the backpacks and police were working to locate them.
White said the suspects, who are not believed to be students at the school, surrendered without incident and are being questioned by police.
Other schools in the area have been checked, White said, and it has not been determined if other schools have been involved.
A Denver Public Schools spokesman said after police have completed their investigation it will determined whether the schools involved will open Tuesday.
