A South Florida couple who ran a "butt doctor" practice out of their home has pleaded guilty to practicing health care without a license.

The pleas came Thursday in Miami-Dade Circuit Court from 55-year-old Samela Hernandez and 59-year-old Pedro Hernandez. The Hialeah couple will serve two years of house arrest, with permission to leave for work, plus payment of restitution.

Authorities say they mainly provided so-called "touch-up" injections to their mostly female customers who had gotten more extensive posterior enhancement work done overseas. The Miami Herald reports they were arrested after an exotic dancer suffered permanent disfigurement.

Investigators also say Samela Hernandez used a silicon-based solution that is legal in her home country of Colombia but banned in the U.S.

South Florida is a hub for illegal butt enhancements.
