New York City madam Anna Gristina pleaded guilty in 2012 to charges related to her allegedly providing prostitutes, including some minor girls, to wealthy, powerful clients, and she claimed to have powerful people protecting her.

Prosecutor Charles Linehan told Merchan they were unable to find any evidence to substantiate Gristina’s claims — caught on wiretaps as long as four years ago — that she had connections and protection from law enforcement.

“Over the years, the defendant made numerous claims that she had connections and influence in any number of city, state and federal agencies, including the NYPD, the FBI, the DA’s office, the governor’s office and Customs, among others,’’ Linehan said.

“We have spent time investigating the defendant’s claim, and we have not found evidence to support any of those claims.

Gristina was arrested in February to much fanfare, with prosecutors claiming she ran the big-bucks hooker ring out of an Upper East Side apartment.

They claimed that a five-year probe by the DA’s public corruption unit turned up hundreds of hours of wiretaps and that the well-connected Gristina laundered millions of dollars while boasting of her ties to top officials and law enforcement. They said she also had minors involved in her operation.

Sheen allegedly refused to use condoms despite his HIV+ status and wanted prostitutes who were "pre-op transsexuals." The madam who provided the prostitutes to Sheen was Gristina.
