(AP) — The chief of the Los Angeles school police department says preliminary information indicates that the female suspect in the Los Angeles middle school shooting is 12 years old.

Television news footage showed officers leading a girl with dark hair away in handcuffs following the shooting Thursday in a classroom at Castro Middle School. Two students were shot and wounded.

The school has about 365 students in grades 6 through 8 and most are Hispanic and many from low-income families.

The Los Angeles Times says at an event last month where good attendance certificates were presented, Principal Erick Mitchell said the campus is becoming a destination for families who want a smaller school setting. He said Castro emphasizes long-term goals such as college and career, and that has improved student behavior.
