A high school on the southeast side was placed on lockdown for most of the day while Tucson Police conducted a search.
The all-clear was declared at Santa Rita High School, 3951 South Pantano Road, at about 2 p.m. after a room-to-room search by Tucson Police ended without any weapon being found.
According to Tucson Unified School District Director of Communications Cara Rene, the lockdown was ordered after someone reported seeing a person remove what looked like a possible weapon from a backpack while walking toward the school this morning.
Police say the weapon was described as a knife or revolver or both.
A TPD news release said no weapons were found and no person matching the description of the suspicious male was found.
The school was searched multiple times by patrol officers, SWAT officers, and K9 officers from multiple law enforcement agencies, the release said.
