Prosecutors in the Robert Kraft case are now alleging that the New England Patriots owner is seen on video engaging in illicit behavior at a Florida spa.

Police say they have a video of the NFL owner paying the front desk before accompanying two women into a room where other cameras show the three engaging in sexual relations, according to Boston’s CBS affiliate.

According to CBS 4 in Boston, “At about 4:45 p.m. on January 19, police say Kraft entered the business and paid in cash at the front desk. Surveillance cameras were rolling as Kraft allegedly undressed, and met with two women in the massage room.

“In that room, Kraft is accused of engaging in sex acts. Court documents allege he handed both women cash before leaving.”

Police also report having tailed Kraft’s Bentley after the incident they claim is seen on surveillance video.

“The front seat passenger was positively identified by his Massachusetts driver’s license as Robert Kraft,” court papers reveal.

Documents also note that police have a second incident on surveillance video showing the NFL owner in a room with a naked spa worker.

Prosecutors warn that their case is not just about Robert Kraft and that Kraft’s inclusion in the case is only a small part of a “larger crackdown on human trafficking and prostitution at at least eight spas in the West Palm Beach area.”

“These cases aren’t about any one defendant, or any group of defendants, the larger picture in which we must all confront is the cold reality that many prostitutes in cases like this are themselves, victims, often lured into this country with promises of a better life only to be forced to live and work in a sweatshop or a brothel, performing sex acts for strangers,” State Attorney Dave Aronberg said during a Monday news conference.

But a spokesman for Kraft categorically denies any wrong doing. “We categorically deny that Mr. Kraft engaged in any illegal activity. Because it is a judicial matter, we will not be commenting further,” the spokesman said.

For its part the league is reserving judgment.

“Our Personal Conduct Policy applies equally to everyone in the NFL,” the league said in a statement. “We will handle this allegation in the same way we would handle any issue under the Policy. We are seeking a full understanding of the facts while ensuring that we do not interfere with an ongoing law enforcement investigation. We will take appropriate action as warranted based on the facts.”

“We are seeking a full understanding of the facts while ensuring that we do not interfere with an ongoing law enforcement investigation,” the NFL added.
