The Loudoun County Sheriff's Office spent the afternoon going over Potomac Falls High School with bomb-sniffing dogs and found nothing, authorities said. Additional deputies will be on hand at the Sterling school on Thursday, June 2, "out of an abundance of caution" though they suspect the threat was likely a hoax.
An administrator at Potomac Falls received a message Wednesday afternoon claiming there was a bomb on campus. They passed the note to the police and started the school's evacuation procedures. Deputies must take the threat seriously even if they don't think it's credible.
Officials with Loudoun County Public Schools worked with the Sheriff's Office to coordinate the evacuation at 2 p.m. They asked parents to avoid the area around Potomac Falls and neighboring River Bend Middle School unless they needed to pick up their child.
"Having extra people and vehicles on campus will impede law enforcement and emergency personnel and hamper the speed of their investigation," Loudoun County Public Schools said in a tweet.
The Sheriff's Office worked with several other agencies to search the school after the students were gone.
