At a Lakewood school Tuesday morning, deputies ran across the campus where simulated gunshots rang in the background.
It was an active shooter training drill.
With Americans still reeling from two recent mass shootings, Los Angeles law enforcement agencies held the drill at Hoover Middle School, bringing together deputies and firefighters from different agencies to train in case of a major emergency.
The drill involved authorities simulating a shooting, bomb threat and fire threat at the school where Los Angeles sheriff's and fire department personnel practiced responding and taking action.
The training incorporated simulated gunfire and injuries as well as role players, including four "bad guys," the Sheriff's Department said.
"Because of the recent events, everyone understands how important this is and how important not only the intervention aspect is, but also the rescue aspect and making sure that not only do we stop the threat as soon as possible, but also get those that are injured help as soon as possible so that they survive," Sheriff's Department Sgt. Mike Harding said.
Authorities said the gunshots heard Tuesday were from “simunition rounds,” which are paint projectiles fired from modified pistols that could cause injury.
The Sheriff's Department hosts these training drills about 12 to 20 times a year.
