Police walked 25-year-old Joshua Zinberg out of the 20th Precinct Thursday.

He’s accused of slashing a tourist across the face on the Upper West Side in a seemingly unprovoked attack.

“I heard the guy scream and I saw him run down the block, but I didn’t realize what it was,” said Upper Westside business owner Stanley Furman.

In what many residents call a safe neighborhood, Furman said he didn’t expect a slashing to happen outside his office.

“All my patients that were in yesterday, they were not happy about this,” Furman said.

Police said Zinberg slashed the tourist Wednesday morning near the intersection of 86th Street and Columbus Avenue.

Zinberg, who police say lives down the block from where the attack happened, is charged with several crimes, including atttempted second-degree murder.

“I was very glad to hear he was arrested. It was scary to hear that something bad could happen in the morning, on a weekday, in broad daylight,” said Upper West Side resident Ally Weiss.

“It’s really, really, scary that it’s happening and it’s so random. You don’t know where it’s coming from,” said Upper East Side resident Wendy Roberts.

The attack comes on the heels of several other slashings across the city, including a triple-fatal-stabbing spree Monday that happened across Midtown Manhattan.

Mayor Eric Adams addressed the recent spat of violence.

“The success of our city has been overshadowed by random acts of violence, and many of them associated with those with severe mental health illness,” Adams said.

Overall, officials said crime is down for the tenth straight month.

NYPD data, as of November 17, shows increases  in rape, robbery and felony assault.

“I’ve been here since the late 70s, so compared to what New York was then, when you literally couldn’t walk across the park past dusk, I would walk across Central Park with complete impunity,” said Upper West Side resident Mark Jenkinson.
