An NYPD surveillance video of a man committing suicide reappeared on a porn Web site yesterday, a day after it had been pulled, police said.

Internal Affairs Bureau detectives ordered the site’s owner to delete the shocking footage of Paris Lane, 22, putting a gun in his mouth and pulling the trigger seconds after he said goodbye to his teenage girlfriend.

Lane’s suicide at the Gouverneur Morris Houses on Washington Ave. in the Bronx was recorded by the NYPD’s viper unit, a squad that videotapes public housing projects as a crime deterrent. Police officers assigned to Public Service Area 7 are being grilled by bureau investigators.

“We want to remind these people [Web site operators] that they are dealing with stolen property,” NYPD Deputy Commisioner of Public Information Paul Browne said last night. “We are making progress in the case.”

Browne said the site’s owner, Paul Ganin, could face charges. The site features sexual depravity and violence. Ganin said Wednesday he had taken the video off his site and would cooperate with police.

Meanwhile ABC News reports the following referring to Ganin as “Dinin”:

The man responsible for the site is making no apologies for it. He says the reason he put it back on his Web site, was that he thought it was newsworthy.

Paul Dinin, Web Site Editor: “They’re basically looking to– they want to vomit, they want to laugh, or they want to **********. And maybe if we’re really lucky we get a combination of all three.”

He also gave us a clue as to who he believes leaked the video, recorded from cameras in the lobby of the Morris Houses, a public housing development in the Bronx.

Paul Dinin: “It was submitted to us by a user of the site who, according to our forums, the person claims to have a known someone on the police force.”

He also claims that police now have the unique Internet address and the e-mail address of the person who leaked the video.

The commissioner of the NYPD says their own internal affairs investigation continues. And he says that even though what happened in the case of Paris Lane is despicable, the surveillance cameras shouldn’t be removed, because they help to fight crime.

Ray Kelly, NYPD Commissioner: “They’re very effective, and it’s a very effective tool. I’d like to get a lot more of them.”
