Police arrested more than a dozen New York state and city elected officials Thursday at 26 Federal Plaza, the Manhattan immigration court and an Immigration and Customs Enforcement (ICE) field office, many as they pressed to gain access to the building’s 10th-floor lockup, where recent court rulings—including a temporary restraining order—directed ICE not to cram immigrants into overcrowded, unsanitary conditions. The lawmakers and other officials, arrested around 3:45 pm local time, say they were “attempting to conduct oversight” following claims that people appearing for court hearings were being confined for hours or days without proper food, medical care, or contact with attorneys. The final four on the list were arrested outside the facility, reportedly by the New York City Police Department. Dozens of New Yorkers who had gathered, holding signs and chanting “ICE out of NY,” were also arrested, officials said. A follow-up demonstration was planned for 6 pm ET at Foley Square, a longtime rallying point for immigrant rights protests in the heart of Manhattan’s Civic Center neighborhood.
