A 19-year-old Missouri woman who called the police during a medical emergency now alleges that one of the responding officers slammed her face into the floor - leaving her with bruises and persistent headaches - and then charged her with assault and resisting arrest.

Kayla Conway called the Pevely, Missouri police department last week out of concern for the safety of her boyfriend, who had overdosed on anxiety medication. The couple recently lost a baby when Conway miscarried six months into her pregnancy, and she was on edge about her boyfriend's health.

Police put the boyfriend in an ambulance, but an officer refused to let Conway ride along with him. His refusal soon became violent, according to Conway.

"He grabbed me by the back of my head and slammed me on the ground and dragged my head across the carpet and put me in handcuffs," she said in a statement to local news.

Conway took pictures of herself showing her bruises and scrapes. She said the abuse, which happened last week, was without provocation. She has lingering migraines because of it.

But police didn't stop there. Conway was eventually taken to the station, placed in a holding cell and charged with assault and resisting arrest.

She has filed a formal complaint asking for the charges to be dropped.

Pevely Police Chief Ron Weeks told The Daily Caller that internal affairs was investigating the incident, and confirmed the charges against Conway. He declined to comment on the matter until the investigation is finished.
