A man detained by the Department of Homeland Security and ICE at the McCook Detention Facility in McCook, Nebraska, filed a habeas corpus petition seeking immediate release from custody. The petition does not detail his nationality, family circumstances, employment, or the circumstances of his arrest. The federal court issued an order to show cause, requiring the government to certify the cause and duration of his detention and justify why the writ should not be granted. The court ordered respondents to file a return with supporting affidavits, a legal memorandum, and copies of any arrest warrant by September 2, 2026. The petitioner may file a reply by September 9, 2026. The court also enjoined the respondents from removing him from the United States or from Nebraska, and ordered that if he had already been removed from the state, he must be immediately returned.
