The bomb threat Tuesday morning at John F. Kennedy High School in Silver Spring was determined “not valid,” and the shelter-in-place, which replaced a lockdown, is no longer in effect, Montgomery County Police posted on social media.
At 9:34 a.m., police said that the school, located at 1901 Randolph Road, was in lockdown, and officers were at the scene, determining if the threat was valid.
At 10:04 a.m., police announced that the lockdown was being downgraded to a shelter-in-place.
This bomb threat follows two bomb threats in the last couple of weeks. The first was at Westfield Montgomery Mall in Bethesda on Aug. 18 and the other was at the Bullis School in Potomac on Aug. 22. Both threats turned out to be not valid, according to police.
