Oneal Ron Morris, known as the “Fix-a-Flat doctor”, was jailed after one of her butt-injections went horribly wrong, the Washington Post reports.

The quack was first apprehended for practising medicine without a license in 2011 and spent 12 months in prison.

She came to prominence after revealing details of her botched operations, including the supposed use of tyre fluid and bathroom caulking to enhance women’s posteriors.

While lawyers were unable to prove exactly what she did, she pleaded no contest to a manslaughter charge in February.

The results came after a medical examiner found that silicon in Shatarka Nuby’s buttocks had leaked to the rest of her body, causing respiratory failure.
