FAIRFAX COUNTY, VA -- Bomb threats made to several schools Friday in Fairfax County, the City of Falls Church, Arlington County and Loudoun County were likely delivered by "robo call," according to a spokesman for Arlington County Police.
The Fairfax County schools where bomb threats were called in Friday are:
Herndon High School, McLean High School, Westfield High School and Potomac, a K-12 private school in McLean.
"All schools have been cleared and are running under normal operations," said Officer Megan Hawkins, Fairfax County Police spokeswoman.
Calls were received at the schools on Friday between 11:22 a.m. and 11:50 a.m., Hawkins said.
The "robo call" technology is similar to that used by marketing companies, when numerous phone numbers can be called at once.
