Authorities are determining to see if they can seek prosecution against the 17-year-old student who is accused of taking a onto the campus last week.
The teen arrested by Glendora Police last week was transferred to Los Padrinos Juvenile Hall in Downey, while the case is being reviewed by the Los Angeles County District Attorney's juvenile division, according to authorities.
The student is enrolled at Bridges Community Day School. School officials found the weapon after the student was seen with a handbag, which are banned along with backpacks and any other such bags.
"Every school is different. In terms of Bridges, where this student is enrolled, we house all their school supplies, so they don't need to take those home everyday," said Sunflower Principal Lisa Raigosa. "That's why in this case, it was obvious there was a handbag and that's not something that we normally see."
According to school officials, a teacher noticed the bag in the girl's possession and advised her to turn it in. The student was cooperative once the device was found, Raigosa said.
The student felt compelled to have the weapon in her possession due to an issue outside of school grounds, Raigosa said. What the issue was has not been revealed.
School and district officials at Charter Oak Unified School District are still working on how to address the incident to parents.
Carrying such a weapon onto school grounds is illegal under California penal code § 626.10.
