A Florida teenager was arrested after he stole an AR-15 out of a police cruiser and later flaunted it online.
The 17-year-old also stole some tactical gear from the unmarked car. He was located after showing off the haul on an Instagram live video. The items stolen from the cruiser were two loaded magazines, a gas mask, Taser, a ballistic helmet, and rifle clips.
He is being held at a juvenile detention center.
