Taylor Swift Alleged Stalker Arrested Again Near Her NYC Townhouse

1/23 -- 7:54 AM PT -- The NYPD says the guy who got dragged away in a police car Monday has been arrested and booked on stalking and harassment charges.

The department says, "Officers were approached by multiple complainants who pointed out an emotionally disturbed male acting erratically at the location. Once officers observed the male harassing multiple complainants, they took him to custody without further incidents; no injuries were reported." The dude's name is David Crowe -- and he's apparently from Seattle.

Taylor Swift had the same dude who was busted at her place this weekend show up on her doorstep AGAIN this week -- and best believe ... cops showed up to handle it.

Law enforcement sources tell TMZ ... the man who was cuffed and hauled away Saturday while trying to access Taylor's NYC townhouse had the gall to swing by her pad yet again on Monday, something her security team and surrounding neighbors immediately noticed.

We're told the head of Taylor's security immediately called cops when the dude arrived, and our sources say everyone reported the same thing ... namely, that he was just lurking.

Of course, considering what just happened a couple days ago with this fella ... that's a huge problem. We're told NYPD officers eventually arrived to the scene, but couldn't immediately find the man -- however, it didn't take long to track him down ... he was around the corner.

Our sources say they found less than a block away from Taylor's residence -- and that's where this interaction with the cops went down, with officers once again throwing him in handcuffs and into the back of one of their police cruisers.

No question about it ... we're told this is, in fact, the same dude from Saturday-- but we're not sure at this point what's gonna happen to him, or if charges are being pressed either.

You'll recall ... when he was originally picked up, cops say they found him fiddling with Taylor's front door, in what police perceived as an attempt to enter without authorization.

When they ran him in their system, they found there was an open warrant for his arrest -- this pertaining to a separate case from 2017 when he failed to show up to court.

It goes without saying ... him coming back to the scene so soon after all that is troubling, to say the least -- and ya gotta figure law enforcement will be a little stricter this time around.

Then again, we know celebs have had a hard time achieving successful deterrents from these sorts of people who appear to be obsessed with them ... with the criminal justice system often failing to protect them from potential danger.

As you know ... Taylor has had a long, documented history with stalkers in her own career ... including one who was previously arrested for trying to get into her Manhattan pad a few years back. Unclear if this guy is that, but already ... he's not setting a good precedent.

Our new documentary, "TMZ Investigates: Obsessed and Dangerous: Hollywood's Stalker Crisis," airs Monday at 9/8c on FOX ... and we break down Taylor's stories and more.
