Belvidere Schools Locked Down For Hours After Threat Reported at High School: Officials

Schools in the Belvidere area were placed on lockdown for several hours Thursday after officials received a 911 call “about a safety concern” at Belvidere North High School, administrators said.

Belvidere School District 100 said around 9:30 a.m. that administrators at the school were working with law enforcement to “investigate the matter immediately" and multiple schools were on lockdown.

Schools that remained on lockdown as of 11 a.m. were Belvidere North High School, Seth Whitman Elementary School and Belvidere Central Middle School. Surrounding roads at the schools also remained closed.

"We currently have no information that the 911 call is credible," the district wrote in an update on Facebook. "We have not found any evidence that aligns with the concern expressed in the 911 call. We are taking every precaution, though, to ensure student and staff safety, which takes time and many people."

The lockdown was lifted around 1:30 p.m., the district said, and Belvidere North High School was releasing students for the building to be cleared.

Students at Central Middle School and Seth Whitman Elementary School would be released at the end of the day, officials said. All after activities were canceled.

Further information on what the threat involved wasn’t immediately known.
