NEW YORK - (AP) - The son of New York City's police commissioner, also a co-host of a popular New York City morning television show, has been accused of sexually assaulting a woman, a person familiar with the investigation said Thursday.

Greg Kelly, 43, was absent Thursday morning from his job as anchor of "Good Day New York" and through a lawyer denied the allegations.

The woman said she had drinks with him on Oct. 8, then went back to her office, where she was assaulted, the person familiar with the case told The Associated Press.

She went to police Tuesday, according to the person, who was not authorized to speak publicly and did so on condition of anonymity. It's not clear why she went to police weeks later or how long they knew each other before the encounter, though she said they had met on the street at some point.

Police spoke to the woman but turned the case quickly over to the Manhattan district attorney's office because of the potential conflict of interest in investigating the son of Police Commissioner Raymond Kelly, the person said.

Kelly, a former Fox News correspondent, is cooperating with the investigation, his lawyer, Andrew Lankler, said in an emailed statement.

Greg Kelly "strenuously denies any wrongdoing of any kind," Lankler said. "We know that the district attorney's investigation will prove Mr. Kelly's innocence." The lawyer didn't respond to questions about the focus of the investigation.
