The Park City Police Department said a passerby reported a person on campus was possibly armed shortly before 2 p.m. Sept. 3.
Park City High School initiated its "secure" protocol, ensuring all students and staff inside and all exterior were locked doors. No one was allowed in or out while authorities investigated and classes proceeded as usual.
The district said the high school returned to normal operations after about 20 minutes when police determined the person was not a threat.
Lt. Danielle Snelson told KPCW the person who was reported did not have a firearm and no arrests were made.
