The Dysart Unified School District lifted its modified lockdown on five of its schools after police investigated an incident in the area Wednesday morning.
There were no threats or concerns to the schools, but the lockdown was conducted out of an abundance of caution, the district had tweeted.
Surprise Police concluded its investigation and there is no longer a threat in the neighborhood.
Cimarron Springs, Sunset Hills and Western Peaks elementary schools, Canyon Ridge School and Willow Canyon High School were under a modified lockdown as Surprise Police investigated a possible suicidal subject in the area, according to a police spokesperson.
Under a modified lockdown, students and staff are moved to or remain in the classrooms and perimeter doors are locked, including the front office. Classroom instruction continues as normal until law enforcement can give an 'All Clear.'
