PASADENA (CNS) - Pasadena High School was placed on lockdown Tuesday while an investigation was conducted into a report that a student had a gun, but no weapon was found, authorities said.
Officers went to the campus in the 2900 block of East Sierra Madre Boulevard late Tuesday morning, according to Lisa Derderian of the city of Pasadena.
Some students thought they saw another student with a gun and authorities were notified, Derderian said. The student was detained by authorities, but no gun was found, Derderian said.
By early Tuesday afternoon, the lockdown had been lifted for all but a small part of the campus, but a search was continuing to determine if a weapon was on the school grounds, Derderian said.
