MOBILE, Ala.—- Police in Mobile, Ala., used pepper spray and a Taser on a deaf, mentally disabled who they said wouldn’t leave a store’s bathroom.

The family of 37-year-old Antonio Love has filed a formal complaint over the incident on Friday.

Police tell the Press-Register of Mobile that officers shot pepper spray under the bathroom door after knocking several times. After forcing the door open, they used the stun gun on Love.

Police spokesman Christopher Levy says police didn’t realize Love had a hearing impairment until after he was out of the bathroom. The officers’ conduct is under investigation.

The newspaper says the officers attempted to book Love on charges including disorderly conduct, but a magistrate on duty wouldn’t accept the charges.
