FORT LAUDERDALE, Fla. (AP) - A Florida woman accused by authorities of illegally injecting toxic substances into women's buttocks as an enhancement procedure has pleaded not guilty.

The South Florida Sun Sentinel reports Oneal Ron Morris sent a written plea of not guilty to a Broward County judge on Thursday.

She faces unlicensed practice of medicine and related charges in Broward County. Morris, who police say was born a man and identifies as a woman, was arrested in November on similar charges in Miami-Dade County.

Her attorney says his client maintains her innocence.

Authorities say Morris injected flat-tire sealant, glue, caulk and cement into women's buttocks. All three victims suffered medical complications and infections.
