Insert Law & Order Donk-Donk Here

I can almost hear Jerry Orbach say it — “Some strange characters hang out in this neck of the woods”*:

The body of a man clad in a kinky black leather mask and decked out head to toe in S&M gear was hanging from a chain-link fence on Hudson Street yesterday — as many passers-by ignored it, thinking it was a Halloween display.

The slightly built, fair-skinned mystery man may have been choked to death by a dog collar around his neck, it’s other end strapped around a 3-foot-tall fence post, police sources said.

The 40ish, tattooed man was found kneeling, braced face-first against the fence in front of 424 Hudson St. at around 6:45 a.m.

In a bizarre twist, the body had been there for at least an hour, dismissed by some who walked past as a quirky seasonal display in an area scattered with S&M and gay bars.

“The body was covered with a black suit and he had a mask on his face,” said deli owner Indra Patel, who first spotted the strangely posed corpse when he opened next door around 5:30 a.m.

“I thought it was a dummy. It looked like a dummy, because every year they do decorations like that. I was wondering why they put up the [Halloween] decorations early.”

Patel said at least an hour went by before a woman walking her dog realized the sidewalk exhibit of a man wearing a pair of leather spiked gloves, chaps and a vest was a real person and called police.

Cops were investigating if the man had committed suicide or died during some sort of bizarre auto-erotic sex game.

. . .

Another witness, Kevin Samuel, 50, a porter for a building across the street, said he had looked at the body several times but it just never clicked that it might be a real person.

“I’m staring at him and I think, ‘Is that a prop or a real person?’ His legs looked like he was twisted on an angle and that he fell in it [the fence]. It looked like he was stuck there and couldn’t get up, like he lost his balance,” Samuel said.

*OK, OK — being Jerry Orbach is harder than it looks!
