A Phoenix high school is notifying parents and guardians regarding a "conflict" involving two of their students.
Alhambra High School Principal Karen Cardenas sent a letter on Thursday about the recent incident.
According to the letter, police were called to campus on Wednesday after a student allegedly attacked another student. Shortly after the assault, one of the students — identified as the "aggressor" by police — was seen near the school shortly after dismissal.
When security officers attempted to approach the teen he allegedly fled. After a brief chase, he was seen by security officers tossing a firearm into a yard.
The gun was found and confiscated by police, however, the student ran away and has not been seen since.
The school is cooperating with police to resolve the issue, Cardenas said. Anyone with information about the incident is asked to contact Phoenix police, Silent Witness (470-WITNESS) or reach out to the school directly.
Students are not believed to be in danger but as a precaution, the school is asking students to be "vigilant" when traveling to and from school.
