The man accused of setting a fire outside a federal building in Manhattan and firing a BB gun toward it was arrested in Brooklyn last year after slashing the tires of a vehicle during a protest, a source close to the investigation told News 12.

New video obtained by News 12 shows Andrew Arrabaca being arrested following the August 2025 incident at Grand Army Plaza.

A source close to the investigation said a vehicle became stuck during a protest when Arrabaca approached it and slashed its tires.

The video begins after the alleged tire slashing and shows a van with two flat tires. The driver is then seen getting out of the vehicle and confronting Arrabaca, who was wearing a green hat and holding a vulgar sign.

Arrabaca was arrested about a half mile away from Prospect Park. The video appears to show officers holding a knife they recovered, along with identification with Arrabaca’s name.

A source told News 12 that Arrabaca was charged with criminal mischief and a hate crime. The hate crime charge was later dropped.

Arrabaca was ordered to attend anger management classes, complete community service, and pay restitution to the victim. He ultimately received a disorderly conduct violation, according to the source.

The Brooklyn District Attorney’s Office said it could not comment because the case is sealed.

Arrabaca, 43, was arrested again Monday after federal prosecutors said he carried out an attack outside the Jacob K. Javits Federal Building in Manhattan.

Prosecutors said Arrabaca fired a BB gun toward the building, poured a flammable liquid outside an entrance, set it on fire and threw fireworks into the flames.

Investigators said Arrabaca deliberately selected a busy entrance and knew people could be injured.

Authorities said the attack was motivated by anti-government and anti-Immigration and Customs Enforcement beliefs.

Investigators recovered a wagon containing a BB gun, a machete, hatchets and a sign that read, “ICE off our streets,” according to prosecutors.

One person was struck in the head by flying debris.

Arrabaca faces a federal charge carrying a maximum sentence of 40 years in prison.
