NYPD commissioner Ray Kelly's son faces sexual assault allegation

(CBS/AP) NEW YORK - Authorities are investigating allegations that the TV show host son of New York Police Commissioner Ray Kelly sexually assaulted and impregnated a woman.

No charges have been filed against Greg Kelly, who issued a statement saying he "strenuously denies any wrongdoing" but has stepped back from his duties as co-host of "Good Day New York" on Fox 5 while the investigation is underway, reports CBS New York.

A woman claims that Kelly, 43, met her for drinks on Oct. 8, and then assaulted her after the two went to her lower Manhattan law office, one person familiar with the investigation told The Associated Press on condition of anonymity. She told authorities she was intoxicated and not capable of consenting to sex, the person said.

She said she became pregnant from the encounter and had an abortion, according to a law enforcement official.

The woman reported the alleged attack on Tuesday to police, who turned the matter over to Manhattan District Attorney's office due to a potential conflict of interest, the person familiar with the probe said. 

The allegations surfaced on Wednesday.

The District Attorney's team is now searching for witnesses who may have seen the two together on the night of the alleged attack as well as any surveillance video of Kelly and the woman near a bar, walking to her office or inside her building, reports CBS New York.

Legal experts said that it may come down to whether investigators believe Kelly's accuser was too drunk to say no.

"These are the worst cases because the fact of the matter is that if he knowingly forced himself on somebody who is saying no even though she started down that road, it's still rape," criminal lawyer Gerald Lefcourt told CBS New York.

It is unclear how long the woman and Greg Kelly knew each other before the alleged encounter at her office, but they were apparently in touch afterward, according to the person familiar with the investigation.
