A chapter of the Alpha Kappa Alpha sorority at a Georgia college is under investigation for allegedly running a prostitution ring to cover the initiation fees.

Last month, Alecia Johnson, the graduate adviser for the Alpha Beta chapter of Alpha Kappa Alpha Sorority, Inc., at Fort Valley State University, resigned after law enforcement launched the probe into the alleged sexual misconduct, reported The Washington Post.

Before leaving the school, Johnson was accused of convincing pledges to have sex for money with local politicians and businessmen in order to pay the fees associated with the sorority, according to Rolling Out.

Despite the allegations, Johnson’s representation has maintained she’s innocent.

“She’s not a pimp, and she’s not a madam. None of that,” Adrian Patrick, Johnson’s lawyer, told Atlanta’s Channel 2. “She’s not guilty. She did not do anything.”

The investigation began after the University Systems of Georgia received two anonymous tips of “alleged wrongdoing” within the Alpha Beta chapter on April 5. A week later, the Georgia Bureau of Investigations announced it was looking into the sexual-misconduct allegations against the chapter, prompting a team of investigators to search Johnson’s home and personal computer for evidence, the Atlanta Journal-Constitution reported.

“We were appalled to learn of allegations of sexual misconduct against a Fort Valley State University employee who also is a graduate member of the sorority,” the national office for Alpha Kappa Alpha said in a statement. “Upon learning of these allegations, we immediately contacted the university and launched an internal investigation, which is ongoing.”

Although it is not clear whether activities at the chapter have been suspended, the sorority did release a statement wherein they maintained that it has a “zero-tolerance” policy for hazing and sexual harassment.
