NEW YORK (AP) — New York City Comptroller and Democratic mayoral candidate Brad Lander has been arrested by federal agents at an immigration court after he linked arms with a person that authorities were attempting to detain. A reporter with The Associated Press witnessed Lander’s arrest on Tuesday. The immigrant Lander escorted out of the courtroom was also arrested. Lander was released from custody after a few hours after spending the morning observing immigration court hearings. He told an AP reporter that he was there to “accompany” some immigrants out of the building. The episode occurred as federal immigration officials are conducting large-scale arrests outside immigration courtrooms across the country.
