SUBWAY CUO-ING NOWHERE

NYPD boss ordered bums’ rush for Blas

The NYPD sergeant who ordered a homeless “sweep” ahead of Mayor de Blasio’s arrival at two subway stations did so at the direction of a boss at NYPD Headquarters, The Post has learned.

But Transit Bureau Sgt. James Lynch’s mistake was putting the order in a memo, which he did, sources said, because the mayor only recently has started riding the rails. “Transit is not used to doing that, so when they got the phone call, they put it in writing, which is probably not the smartest thing to do,” one source said.

Lynch had a cop send out the e-mail, which directed officers to roust vagrants from the Fourth Avenue/9th Street and Jay Street/ MetroTech stations on Sunday.

The Post obtained the e-mail following a series of City Hall denials that it existed.

Lynch issued his directive to Transit District 30 on orders from a superior at the Joint Operations Center at NYPD Headquarters, sources said. “This was a direction Lynch was given. There’s a layer above Lynch,” a source said.

Cops have been rousting vagrants to keep them away from de Blasio for years, police sources said. The Post reported a sweep of Washington Square Park two hours before the mayor strolled through en route to a Ramadan event in July 2015, for example.

“They had to clear all the homeless out before he got there,” a source said at the time.

The clean-up operations typically follow a call to a local precinct from de Blasio’s NYPD “advance team,” sources said.

“They’ll tell us to make sure it’s secure, to make sure it’s clean, free of homeless, anything like that. They say, ‘Make sure it looks presentable,’ ” one source said.

Boy, is that one subway press conference proving a window into Mayor de Blasio’s misgovernment. The news that his entourage actually stopped the train for the mayor’s convenience is only the latest outrage.

But a truly telling one. Mayor Mike Bloomberg was a multibillionaire, but he never pulled this stunt in his 12 years of commuting by subway from 72nd Street to City Hall. Whereas Mayor “Two New Yorks” took the privilege on one of his first ventures underground.

Then, too, The Post has learned that it’s routine for the NYPD to clear out the homeless in advance of de Blasio’s public appearances. The “sanitizing” got exposed this time only because the department’s Transit division hadn’t been clued in to do it without leaving a paper trail. (And, of course, Transit was in the dark because de Blasio never takes the subway.)

All this on top of City Hall’s days of denial that the homeless had been rousted out that day, followed by de Blasio’s “I don’t care” re- sponse to the e-mail that proved otherwise.

Sadly, it’s possible the mayor had no idea all this was being done for him: He’s that deep in his bubble.

But that helps explain why he’s been so clueless about the problems facing regular New Yorkers: The subway crisis caught him by surprise because he never rode the rails after winning his high office.

And, with cops moving the homeless out of view whenever he stepped outside, he may truly have believed it all those months that he was denying that street homelessness was soaring. He wasn’t seeing it, except in the pages of The Post, and failed to realize that the actual “fake news” was his own sheltered existence.

Of course, none of this excuses his habit of blaming the messenger. After the fourth or fifth time you claim a newspaper is making stuff up, only to be confronted with hard evidence to the contrary, shouldn’t you realize you’re out of touch?

Not our “progressive,” privileged mayor. He just doesn’t care.
