A day after an explosive device prompted evacuations at a San Jose high school, the campus remained closed, and investigators were searching for the culprit.
Students and staff at Oak Grove High School were evacuated Tuesday afternoon as the San Jose Police Department's bomb squad investigated a suspicious device.
The bomb squad determined the device to be a functioning explosive, prompting the evacuation, and hours later rendered it safe, police said. A search of the campus was conducted, and no additional devices were located.
On Wednesday, the Eastside Union High School District decided to keep the school closed and said it would resume classes Thursday, according to the school's website.
Santa Clara County and FBI crime labs were conducting a full analysis of the device and its contents.
The school at 285 Blossom Hill Road was evacuated sometime after 1:30 p.m. to a nearby park at Coy Drive and Judith Street, San Jose police said.
Initially, police issued a precautionary shelter in place for the school just before noon.
By about 6 p.m., police said the bomb squad rendered the suspicious device safe and cleared the campus.
Anyone with information on the case or with video surveillance of the area is urged to contact Detective Joel Martinez of the San Jose Police Department Assault’s Unit at (408) 464-8379.
