The precautionary lockdown of Jamestown High School was lifted at 12:34 p.m. after Jamestown police officers and state troopers cleared the area around the building.
Just before noon, a 911 call reported a home invasion at a Franklin Street home and three suspects are still being sought in connection with the incident.
Principal Joe Yelich said the school resource officer made him aware of the incident and JHS went into precautionary lockdown mode as a result.
No one was injured during the home invasion, police said, and it likely wasn't a case of random violence.
The Jamestown Police Department is continuing to investigate the incident and anyone with information is asked to call 483-TIPS.
