FORT LAUDERDALE, Fla. (AP) — Prosecutors aren’t filing charges against a Florida teen arrested after deputies pepper-sprayed him and slammed his head into the ground.

The Broward County State Attorney’s Office released a statement Tuesday that no charges would be filed against the 15-year-old following last week’s altercation in Tamarac. The prosecutors say an investigation of the deputies continues.

The deputies responded to a fight Thursday outside a McDonald’s where about 200 students had gathered. Authorities say the teen picked up a phone belonging to a student being detained.

Video shows Sgt. Greg LaCerra sprayed the teen after he stood up and appeared to say something. LaCerra then threw him down and Deputy Christopher Krickovich slammed his head twice and punched him. The teen wasn’t seriously hurt.

Krickovich was placed on suspended status. His union says he acted in self-defense.
