An off-duty police officer is under investigation after he slammed a woman to the ground over her refusal to wear a face mask, according to Complex.

The officer, who has yet to be identified, also works as a security guard for a Birmingham, Alabama, Walmart where a woman became upset after she was asked by a store employee to put on a face mask before entering. Sergeant Rod Mauldin said the woman refused and began yelling expletives at customers and employees, NBC News reports.

In a video of the incident, the officer is seen attempting to detain her. He then grabs her between the legs, picks her up and slams her to the ground.

Mauldin said the officer used a “takedown measure” to detain the woman because of “other threat factors in the store.”

The woman was not injured and refused medical treatment, according to NBC News. She was arrested for disorderly conduct and resisting arrest among other charges. A use-of-force investigation was launched, per Birmingham police department protocol.

Although Gov. Kay Ivey has relaxed Alabama’s stay-at-home measures, which include a recommendation to wear face masks in public, a Birmingham ordinance requires citizens to wear facial coverings, according to the National Law Review. That specific Walmart also requires customers to wear a mask, per TMZ.

“The Birmingham Police Department has maintained a consistent community-oriented educational approach to the surrounding circumstances of COVID-19,” a Birmingham police spokesperson told TMZ. “Our records indicate we have not issued any citations or made arrests as it relates to the shelter in place ordinance or the face-covering ordinance. We have made a valiant effort to gain voluntary compliance and we will continue to work cohesively with the community.”

Police officers around the country have been under fire for their treatment of people not wearing masks in public or violating social distancing orders.

The Southeastern Pennsylvania Transit Authority (SEPTA) changed its policy requiring passengers to wear face masks while onboard after a video surfaced of officers forcibly removing a man from a bus for not wearing a facial covering, as Blavity previously reported.
