SIMI VALLEY, Calif. — A 30-year-old man identified by law enforcement as a prolific repeat offender was arrested near a local elementary school on Wednesday morning after entering the campus, exhibiting suspicious behavior in a restroom, and leaving behind suspected narcotics before fleeing the scene.
Officers with the Simi Valley Police Department located and apprehended the suspect, identified as Armando Valle-Martinez, following a rapid area search near the intersection of Yosemite Avenue and Los Angeles Avenue.
The July 29, 2026, incident at Katherine Elementary School marks the suspect’s eighth arrest since May 2026, triggering widespread community concern and prompt intervention from local law enforcement and probation officials.
Suspicious Behavior on Campus Leads to Rapid Police Response
According to police reports and eyewitness accounts, Valle-Martinez entered the grounds of Katherine Elementary School on Wednesday morning. Once on campus, he entered a restroom facility and reportedly undressed with the door facing an employee workstation open before leaving a quantity of illegal narcotics inside and fleeing the premises.
School officials and witnesses immediately notified emergency dispatchers. Because Simi Valley Unified School District campuses were closed for summer break at the time of the incident, no students were present on campus during the disturbance.
Responding officers quickly established a perimeter in the surrounding neighborhood. Within a short time, officers spotted Valle-Martinez walking near the intersection of Yosemite Avenue and Los Angeles Avenue and took him into custody without further incident.
Following an on-scene investigation, Valle-Martinez was booked into custody on multiple charges, including prowling and felony narcotics possession.
