Woman Ran Manhattan Prostitution Ring, Prosecutors Say A woman ran a multimillion-dollar prostitution ring in Manhattan and bragged that she had contacts in law enforcement who would tip her off if she came under scrutiny, prosecutors say. The woman, Anna Gristina, 44, was charged with promoting prostitution, a case built from a five-year investigation by a unit of the Manhattan district attorney's office that pursues cases against the police and other uniformed city workers, according to a transcript of her arraignment on Feb. 23. She pleaded not guilty. A co-defendant has yet to be arrested and has not been named. Ms. Gristina's lawyer, the district attorney's office and the police declined to comment on Monday. Ms. Gristina said she had arranged trysts for 15 years, many of them at an apartment on the Upper East Side, Charles Linehan, an assistant district attorney, said in court. Minors were involved in some of the encounters, the prosecutor said. During hundreds of hours of surveillance, Ms. Gristina was heard saying that "she has connections in law enforcement who are poised to help her out, to let her know if there is trouble," Mr. Linehan said, according to the transcript of the arraignment. The Web site DNAInfo first reported Monday on the case against Ms. Gristina, who is being held on $2 million bail. If convicted, she could face up to seven years in prison. Ms. Gristina, a British citizen with legal United States residency, is a mother of four and lives in Monroe, N.Y.
