Official: Accuser of NYPD boss' son had abortion NEW YORK - The son of New York City's police commissioner has been accused of sexually assaulting a woman who told authorities she got pregnant from the encounter and had an abortion, people familiar with the investigation said Thursday. Greg Kelly, 43, was absent Thursday morning from his job as anchor of the popular local morning show "Good Day New York" and through a lawyer denied the allegations. The woman told authorities she met Kelly for drinks on Oct. 8, then went back to her law office in lower Manhattan, where she was assaulted, one person familiar with the case told The Associated Press. She said she became pregnant and had an abortion, according to a law enforcement official. It wasn't clear whether the woman supplied any medical evidence to authorities to support her claim. NYPD chief keeping quiet on son's sex probe NYPD commissioner's son accused of sex assault Police spoke to the woman but quickly turned the case over to the Manhattan district attorney's office because of the potential conflict of interest in investigating the son of Police Commissioner Raymond Kelly. Lew Leone, the general manager of the local Fox station, said, "Greg Kelly has requested some time off." At some point, the woman's boyfriend learned the story and became enraged, the person said. The woman's boyfriend confronted the elder Kelly at a recent public event, police spokesman Paul Browne said. He said he could not comment on the investigation because of the potential conflict of interest. Mayor Michael Bloomberg Thursday that he "thought the police department did exactly what they should do" by turning the matter over to the district attorney. It wasn't immediately clear how much time elapsed between the man's remarks to the commissioner and the woman's decision to go to a police station Tuesday, nor why she had waited for nearly three months after the alleged attack to make a report. It's also unclear how long the woman and Kelly knew each other before the alleged encounter at her office. The identity of the woman has not been released, and the AP does not name people who report being sexually assaulted unless they agree to be identified or come forward publicly. In 2007, the television show "Extra" identified him as the most eligible anchorman on TV. The allegations about Kelly's son are the latest potential public relations challenge. Also Thursday, about 20 activists held a news conference on the steps of City Hall and criticized Ray Kelly for giving an interview to the producers of the movie "The Third Jihad." They said the film encourages Americans to be suspicious of all Muslims. Kelly has apologized for the interview.
