A Columbia University undergraduate, Elaina Aghayeva, was detained early Thursday morning after DHS agents allegedly misrepresented themselves as police to access her off-campus residence, drawing immediate responses from campus leaders and city officials.

Mamdani publicly said he warned Trump about the arrest, and Trump allegedly agreed to release Aghayeva promptly, though the two remain at odds on other issues.

Acting Columbia President Claire Shipman said the university is gathering information, offering family contact, and providing legal support while withholding details about Aghayeva’s identity or immigration status.

Reporting indicates the story is developing, with updates forthcoming as more information becomes available.

The episode sits within a broader national debate over immigration enforcement, campus safety, and related legal rulings, including scrutiny of agents’ tactics.

State and university policy developments reflect ongoing tensions as colleges balance the pressures of immigration enforcement with due process and campus safety.

Context notes highlight discussions about how immigration enforcement is evolving under the current administration and concerns from students about housing protections and safety.

DHS and certain brands did not immediately comment; Columbia and city reporters continue covering developments.

NYC officials and Columbia leaders criticized ICE’s actions and urged adherence to legal protocols, including the necessity of warrants for accessing housing.

Columbia scheduled an emergency noon vigil to mobilize the campus in response to the incident.

The coverage includes related reporting by The Associated Press and reactions from the university community as the situation unfolds.

Mamdani described ongoing disagreements with Trump but indicated openness to collaboration if it benefits New York City.
