A bomb threat forced school officials to evacuate classrooms and send students home Monday in Fairfax County.
The bomb threat came to the school by email, Torre said.
The 10th largest school district in the country, Fairfax County schools face nearly daily threats. Security officials have said that threats come in frequently through the Internet and social media and that they investigate about 100 cases each year.
Earlier this year, fake bomb threats closed schools in six states, and in 2015 a threat forced school officials in Los Angeles to cancel classes for the second largest school system in the country.
Police said the bomb threat came to the school shortly after 8 a.m. Monday. Fairfax County police tweeted that first responders were on the scene at McLean High School assisting with the bomb-threat investigation.
Police spokesman Don Gotthardt said that police performed an initial sweep of the school and did not locate any explosive devices. Gotthardt said that out of an abundance of caution the department’s explosive disposal team also is conducting a search of the school with a bomb-sniffing dog.
