Fla. Stat. § 901.16

A peace officer making an arrest by a warrant shall inform the person to be arrested of the cause of arrest and that a warrant has been issued, except when the person flees or forcibly resists before the officer has an opportunity to inform the person, or when giving the information will imperil the arrest. The officer need not have the warrant in his or her possession at the time of arrest but on request of the person arrested shall show it to the person as soon as practicable.
