A 14-year-old former student is in custody after allegedly shooting a current student in the arm with a rifle at Highland High School in Palmdale, CA, Friday morning, sparking a major response from deputies.

Deputies were sent to the school after receiving a report of an "active shooter" about 7 a.m., Los Angeles County Sheriff's Department Capt. Darren Harris said.

Authorities responded within five minutes, soon learning that a 14-year-old armed with a rifle had fired and struck another student in the arm, Harris said.

The wounded teen was taken to a local hospital in good condition and is expected to make a full recovery, Harris said. Authorities initially said the victim was also 14, but later stated he was 15 years old, reports KTLA .

The shooter fled the campus with the gun but was taken into custody some distance away, the captain said. CNN reported the teen was caught near a Vons grocery store.

An off-duty Los Angeles Police Department traffic officer who "was in the right place at the right time" apprehended the teen, a desk officer for LAPD's Valley Traffic Division confirmed.
