MTA ‘troubled’ by ‘Walking Dead’ subway grate video

A video prank for “The Walking Dead” in which actors playing zom⛄bies lurked beneath a subway grate and scared New Yorkers is under investigation by city officials, authorities saꦰid.

“We are deeply troubled by this video,” an MT🌸A spokesman said Sunday. “We have forwarded it to the NYPD and are also conducting our🀅 own investigation.”

The video promoting AMC’s hit postapocalyptic zombie-invasion series — which returned to the air with new episodes S🎃unday — was posted to YouTube Wednesday and garnered♏ more than 3.1 million views.

The clip shows people shrieking and bolting as “zombie” hands suddenly💎 claw at them through a sidewalk subway grate on 14th Street at Union Square.

It also shows preparation for the video shoo🍬t from the previous night, in which crews pr💎y open and climb into the grate under cover of a lighted tent.

The Manhattan ad agency that staged the stunt did not have permission, WPIX reported, although policeꦛ and transit officials told The Post they are still trying to determine if that’s the case.

H. Tony Berger, C🌃EO and founder of Relevent, the NYC ad agency that made the film, defended his 💟work.

“I can’t go into specific details,” he said. “But I firmly and stro🌼ngly believe that what we did — the shoo t— was executed legally and in a💯ccordance with city policies.

Cops said they hadn’t received a formal complaint from the MTA as of Sunday, a police source told the Post. But accessing subway grates and filming on city property without permits could result in c🌟harges of trespassing, criminal mischief and disorderly conduct, the source said.

The city recently has turned into a pla๊yg꧃round for professional video pranksters. Another ad agency, ThinkModo, had viral hits with two recent movie promotions.

One, for the horror flick “Devil’s Due,” sprang a hideous robot baby onꦺ unsuspecting New Yorkers who peek🎀ed into what looke♍d like an abandoned stroller.

The “Devil Bওaby Attac♎k” video has gotten more than 42 million views since Jan. 14.

The other, for last fall’s remake of “Carrie,” turned a West Village coffee shop into a house of horror♔s.
