BELVIDERE, Ill. (WIFR) -- Belvidere School District 100 has lifted a lockdown for Belvidere North High School and surrounding schools after a 911 call prompted a "safety concern" for the district.
The lockdown included Belvidere North, Belvidere Central Middle School, and Seth Whitman Elementary School. It was lifted shortly after 1 p.m.
Belvidere North High School is dismissing early, while Seth Whitman and Central Middle School will dismiss at their normal schedule.
Buses are ready for students to take their regular route home. High school students who need to wait for a ride will be waiting at the stadium for pick up.
Boone County Sheriff David Ernest said school grounds were "secure" shortly after 10 a.m., but the three schools remained on lockdown for several hours. Police say there was no evidence found to support claims from a 911 call.
Ernest says the call that prompted the lockdown is still part of an active investigation. If you have an information, contact the Boone County Sheriff's Office or Belvidere police.
