Phoenix police are investigating a threat written on a bathroom wall at Central High School.
Phoenix Union High School District spokesman Craig Pletenik said the threat was found at about 8 a.m. Monday.
Few details have been released, but Sgt. Trent Crump said officers are looking into a perceived threat written in a bathroom stall.
Parents received a robocall alerting them to the threat around 9:45 a.m.
Pletenik said school officials and police do not believe there is imminent danger, but the situation is being reviewed.
The school, which is located on Central Avenue south of Camelback Road, is on a modified lockdown and students are to stay in their classrooms. Pletenik said parents should not go to the school to pick up their kids.
Information will be updated as it becomes available.
