An investigation into the shooting of an unarmed black man as he lay on the ground with his hands in the air is being undertaken by the Florida Department of Law Enforcement, North Miami's police chief said on Thursday.

A cellphone video showed behavioral therapist Charles Kinsey with his hands extended above his chest moments before a bullet struck his leg. The shooting occurred in North Miami while Kinsey was trying to get an autistic man back to a nearby group home from which he had wandered.

Kinsey works at the home, which is operated by the Miami Achievement Center for the Developmentally Disabled.
