MIAMI, FL – A man accused of injecting a woman’s buttocks with a mix of cement and tyre inflater has been arrested. Oneal Ron Morris, 30, was detained in Miami on Friday and charged with practicing medicine without a license and causing serious bodily injury.

The woman, who paid $700, later suffered with abdominal pain, infected sores and flu-like symptoms. Police photographs suggest that Oneal Morris may have had a similar procedure done on himself.

Detectives describe Oneal Morris as a transgender man who dresses as a woman and claim he used a tube to inject a woman in several places on her buttocks. Her body was filled with a mixture that included cement, mineral oil and flat-tire sealant and the incisions were apparently sealed with superglue.

Sergeant Bill Bamford, from Miami Gardens Police, said that when the pain had become too much Oneal Morris had told the woman: “Oh don’t worry, you’ll be fine. We just keep injecting you with the stuff and it all works itself out.”

The procedure originally took place in May 2010 and investigators have been looking for the suspect for more than a year.

Police said the woman – who was referred to Oneal Morris by a friend – ended up at Tampa General Hospital with life threatening symptoms, including pneumonia and a MRSA infection.

“That cocktail had serious complications and serious effects on this young lady,” said Sergeant Bamford.

The American Society of Plastic Surgeons has recently warned about the dangers of ‘pumping parties’, where people gather for cheap silicone injections in body parts like the buttocks, breast or chin. It says that often those carrying out the procedures are not qualified and the conditions not sterile. Police believe there may be more victims and are urging any other possible victims to come forward.
