After more than four hours of investigation, Pleasanton police said there was no evidence of any bombs at Amador Valley High School on Friday, though all classes were canceled.
The news came after a threatening email was sent to the principal about 6:30 a.m. Though the campus was re-opened, school leaders decided not to hold any lessons on Friday, though all other schools in the Pleasanton Unified School District were operating normally, district officials said.
Lt. Jeff Bretzing said that the principal of the school received an email before 7 a.m. that threatened a bomb, and that students were told to stay away from the campus at 1155 Santa Rita Road as police and their K-9 unit swept through each classroom. The Alameda County Sheriff's Department Bomb Team was also called to help.
Principal Tom Drescher told NBC Bay Area that the email threatened "numerous bombs on campus."
Nikki Brown told NBC Bay Area that she got an automated call just after 7 a.m. from the school, telling students not to come to school because of a bomb threat. She has two teens at the school and said she wasn’t really nervous, and she was glad she got the call before driving to campus.
