The New South Wales police force has launched an internal investigation following a transgender woman’s report of police brutality.

Indi Edwards, 46, said she was assaulted by police in her apartment in April after she called the confidential counselling phone service Lifeline.

Soon after she hung up the phone, four police officers charged into her apartment, threw her onto her bed and handcuffed her, she told Australian news outlets.

She was reportedly then dragged out of her apartment and thrown into a police van.

“It was absolutely humiliating because I was half naked and the whole street could see,” Edwards said. “I was freezing cold, dragged through the rain with hardly any clothes on.”

Edwards was taken to Sydney’s Concord Hospital, where she was assessed as being of no danger to herself or others before being discharged.

An NSW police spokesperson told Australian journalists the matter was being investigated.
