One of the most corrupt cops in the history of the Big Apple has been banned from police headquarters after a brazen visit in which he photographed himself for Instagram inside the NYPD’s Lower Manhattan nerve center.
Disgraced ex-cop Michael Dowd, 62, is now pictured on signs posted at security booths near the public entrance to One Police Plaza, photos of which were obtained by The Post.
“Terminated from the NYPD and convicted Felon,” reads one of the notices. “If he attempts to gain access to [headquarters], MUST STOP DO NOT ALLOW ENTRY.”
Dowd was fired from the force after he was convicted of shaking down drug dealers, stealing their stock and selling it himself when he worked as a cop in Brooklyn during the late 1980s and early ’90s.
He spent 12 years in prison — but it looks like the NYPD hasn’t quite forgiven him.
The signs — which include the handwritten demand “Do not remove from booth” — are likely the product of Dowd’s surprise April 14 visit to the Shield Unit, which is on the second floor of police headquarters.
The shamed former officer — whose illegal habits were detailed in the 2014 documentary “The Seven Five” — posted a photo of himself to Instagram that day, alongside a snarky caption.
“At @1policeplaza finally getting my exit photo,” Dowd wrote. “#NYPD #thesevenfive.”
“I’m a funny guy,” Dowd told The Post at the time. “I have a sense of humor. I was poking fun at myself. Had I done the right thing I would have been able to honorably take a pension.”
Dowd said he was there with a retired cop who needed a new ID. The cops working the entrances didn’t hesitate to let him in, he added.
But some didn’t think Dowd’s antics were so funny.
“It’s a bad look for the police department,” said a retired cop who worked during Dowd’s tenure.
“One of the most corrupt cops you’ve had taking pictures and making jokes,” the cop said. “They should investigate who let him in there.”
NYPD brass took notice.
Following the visit, Police Commissioner Keechant Sewell ordered a review of the process by which retirees’ guests are granted access, a police source said.
The new signs also banned Theodore Hanlon, a retired NYPD sergeant who is “known to fraternize with convicted felon Michael Dowd.”
Dowd did not return a request for comment Sunday.
