Mayor Eric Adams claimed that the masked firebug who torched nearly a dozen NYPD vehicles in Brooklyn Thursday morning was linked to the violent anti-ICE riots in Los Angeles – but sources told The Post there is little to back up that assertion.

“We have reasons to believe the person who participated in this act is connected to some of the protests that [are] taking place in Los Angeles and throughout the entire country,” Adams told reporters of the arson, which took place in a Bushwick lot about a block from the 83rd Precinct stationhouse.

Hizzoner would not elaborate further on how that connection was established, but said “there’s a clear indication that someone that had firsthand knowledge of this and taking credit for it, and that’s going to be part of our investigation.”

Sources, however, say the mayor was referring to a screed posted on X by the group Unity of Fields announcing the arson, and listing the top motive as “solidarity with the uprising happening in Los Angeles where community and rebels are fighting Amerikkan pig forces.”

“From one cop city to another, death to the pigs and the surveillance state,” the poster wrote.

But the legitimacy of that post – and whether the writer actually took part in the LA riots – has not been confirmed, police sources said.

The suspect, dressed in all black, tried to open the lock to access the lot — but when he could not, he climbed the fence and spent about 40 minutes inside, sources said.

A total of 11 vehicles were damaged and 14 were impacted in the early-morning fires, but thankfully no injuries were reported, Adams said.

Cops also discovered three incendiary devices that did not go off placed on three separate cars in the lot soon after two people wearing masks and gloves were seen running away, sources said.

Photos from the scene obtained by The Post show spheres with wicks sticking out above a tire on the cars — similar to fire starters that can be bought at Home Depot.

“On scene, we found three vehicles that did not sustain fire damage with ignited fire starter balls and haystack bundles scattered across the rear passenger tires, the front tires, and the windshields,” Police Commissioner Jessica Tisch told reporters.

“In total, we found 12 unignited fire starter balls and 10 ignited haystack bundles, as well as a torch-style lighter.”

No arrests had been made in the arson by Thursday afternoon, and the motive was not immediately established.

However, a flyer taped to a wall directly across from the police station accuses officers of the 83rd Precinct of breaking up Puerto Rican Day festivities on Sunday night, injuring revelers.

The fliers called for resistance against the police, and tied in the anti-ICE protests that have spread from Los Angeles to New York City, as well as global anti-Israel protests.

Meanwhile, investigators are looking for any video that shows where the firebug went after leaving the lot.

Adams said the arsonist will ultimately be brought to justice. 

“This is a felony. It is arson, and we’re going to treat it as such,” the mayor said. “And I want to be loud and clear, the next few days we are hearing a lot of intelligence about individuals [who] want to use this moment to carry out some form of havoc in our city. It’s not going to happen. And things like this are unacceptable.”
