San Mateo High School Evacuated After Bomb Explosion

Students and employees at Hillsdale High School at 3115 Del Monte Street in San Mateo were evacuated to nearby Abbot Missle School. According to the CHP, there are reports of a pipe bomb inside the high school. KRON 4 reports that a suspect has been arrested.

One student, Cody, who was interviewed by KRON 4 News, says he saw a student "run down the hall" while trying to light pipe bombs and throw them. Then, another overexcited teenager tells KRON 4 that she heard people got shot and heard they brought in chainsaws too. (This wasn't actually the case, the shooting -- but, God, we LOVE teenagers.) He also heard an explosion. No reports of any injuries.

CBS 5 have a chopper live on the scene.
