Ala. Code § 15-10-4: Arrest Without Warrant - Duty of Arresting Officer; Authority of Officer to Break and Enter Dwelling House.

When arresting a person without a warrant, the officer must inform of his authority and the cause of arrest, except when the person is arrested in the actual commission of a public offense or on pursuit. In making a warrantless arrest, an officer has authority to break open an outer or inner door or window of a dwelling house if, after notice of his office and purpose, he is refused admittance.
