The number of arrests made in connection to the day of city transit chaos caused by cop-hating vandals jumped to at least 16, authorities said Saturday.

The MTA detained at least 11 people, arresting three and issuing summons to eight others, most for disorderly conduct during skirmishes with radical agitators flooding Grand Central Terminal and other stations Friday.

The NYPD said it made 13 arrests — nine men and four women — on charges ranging from criminal mischief, obstructing governmental administration, assault, disorderly conduct, and resisting arrest. They also issued 11 court summons, officials said.

The demonstration, organized by the group Decolonize This Place called for a free transit system, with “no cops.” Beginning in the morning, protestors vandalized stations throughout the city, and held hateful signs with messages such as “F–k the police fight the power” and “No fare no cops.”

They also poured glue and honey into turnstiles to jam them, officials said.

One protestor threw a heavy object through the window of a storefront in Lower Manhattan, shattering the glass and sending glass shards into the face of a woman inside, authorities said.

In Brooklyn, cops busted Jasper Skelton, 20, for allegedly pointing a laser beam into an officer’s eye on the sidewalk outside a building on Fulton Street in Crown Heights, police said.

He fled, but was charged with assault after police caught up with him and found the laser in his pocket, prosecutors said.

At Skelton’s arraignment Saturday, prosecutor Jordan Rossman told the court Skelton had been behind a “F–k the police” banner during the laser attack — though lawyer Moira Meltzer-Cohen argued that it was “irrelevant” to his bust.

Skelton was ultimately released without bail and is expected back in court on April 3.

The Police Benevolent Association called out the protesters’ twisted agenda, tweeting out a photo of a knife with ‘FTP’ and ‘aim for the neck’ inscribed.

“The anti-cop agitators causing havoc in our city tonight have made it clear that violence against cops is on their agenda,” the union wrote.
