Nieto, of Corona, Queens, was charged Friday with assault, unlawfully practicing medicine and endangering the life of Augusta Velez during the botched surgery, reported the New York Daily News.
For the butt enhancement procedure, the 23-year-old Velez went to Nieto's spa, Perfect Image Stethics. According to the newspaper, Nieto performed liposuction on the patient's stomach March 20, then re-injected the fat where Velez wanted it, in the buttocks.
The end result was not the J.Lo booty of her dreams for $500, but intense pain and high fever. The paper says Velez had to have an additional surgery to avoid a life-threatening septic infection.
It is allegedly not Nieto's first bad ending. Another woman previously pressed charges against Bell Stetika Esthetics, also owned and operated by Nieto, claiming that she suffered disabling injuries following her butt augmentation, according to The Daily News.
Prosecutors believe there may be more victims of Nieto's botched butt enhancements.
