SCHENECTADY -— All three campuses of Schenectady County Community College were evacuated as a result of bomb threats police say were called into the school shortly before noon Tuesday, city police Lt. Mark McCracken said.

A total of three calls, the first received at about 11:55 a.m., were placed by an unidentified man who said multiple explosive devices had been planted on campus, police said. The caller said devices would detonate and urged an evacuation of campus.
