Mayor Zohran Mamdani condemned the immigration enforcement that led to a tense standoff between New Yorkers, the NYPD and federal immigration agents outside of a Brooklyn hospital Saturday night.

The mayor said the NYPD did not coordinate with U.S. Immigration and Customs Enforcement in the agency’s civil enforcement, and that police officers responded to protests outside the Wyckoff Heights Medical Center in Bushwick.

Immigration authorities had arrested Chidozie Wilson Okeke, a Nigerian citizen accused of overstaying a tourist visa, and brought him to the hospital after he requested medical treatment, the U.S. Department of Homeland Security said in a statement.

“I’ve made very clear that our laws leave nothing, no room for interpretation about the fact that our NYPD will not participate in civil immigrant immigration enforcement,” the mayor said when asked about the incident at an unrelated press conference Monday.

Since President Donald Trump took office last year, immigration authorities have stepped up enforcement in the city and across the country, though heavy enforcement has dropped after federal authorities killed two protesters in Minneapolis earlier this year. In New York, city employees and agencies are banned from aiding in civil immigration enforcement in most cases because of sanctuary city laws.

The NYPD said they arrested nine people outside of the medical facility Saturday night as anti-ICE demonstrators attempted to disrupt and block immigration authorities from leaving the area with a man they had arrested.

Videos from the demonstration taken by bystanders, distributed on social media and shared with Gothamist by the New York Immigration Coalition show a chaotic scene as protesters attempted to block cars from leaving the hospital and NYPD officers cleared them from the roadway.

In one video, an NYPD officer throws a demonstrator to the ground in the street. Mamdani said the video is “incredibly disturbing” and is being investigated.

At a separate event on Monday in Bushwick, immigration advocates and local officials also condemned the action and praised the effort by New Yorkers to disrupt ICE.

“Bushwick is very, very clear: we do not want ICE in our neighborhood,” said City Councilmember Sandy Nurse, who represents the neighborhood. “And not only are we saying it, we are organized.”

Brooklyn Borough President Antonio Reynoso also spoke at the event and called for ICE to be eliminated.

“We want to make sure that everyone in this entire country knows that in New York City, we want to abolish ICE,” Reynoso said.

An NYPD spokesperson said eight people were arrested and charged with resisting arrest, obstructing governmental administration, reckless endangerment, and criminal mischief.

One other person was given a summons and released.
