NEW YORK (AP) — A person set off fireworks and started a fire Monday morning outside a New York building housing an immigration court and other government offices, according to federal authorities.

As the flames erupted outside an entrance to the building at 26 Federal Plaza, the person was tackled by a security officer and taken into custody, video shows. Their name has not been released and no charges have been announced.

The lower Manhattan building, 26 Federal Plaza, has become a focal point for demonstrations against the immigration policies of President Donald Trump’s administration.

The individual in custody was carrying anti-ICE material, according to preliminary information gathered by law enforcement and described by a person familiar with the matter who was not authorized to discuss an ongoing investigation by name.
