JACKSONVILLE, Fla. - The Jacksonville Sheriff's Office is holding an active shooter training exercise on Friday at First Coast High School, 590 Duval Station Rd.

Over 50 law enforcement officers were on hand for the drill.

Student Nijat Khalif was an actor for the drill.

"Even though we knew it was a drill, it is still a scary situation," she said.

Sheriff Mike Williams said the exercise is to get officers and school administrators on the same page and ensure kids are safe at all times.

JSO said there will be an increase in police presence, security and firefighters in the area as a result of the training. Because of this, JSO tells the public they shouldn't be alarmed.

The training exercise is not open to the public.
