A federal prosecutor asked a judge Thursday to dismiss an asylum seeker’s request to be released from custody after he was arrested by immigration agents this week during a routine check-in.

Yanick Joao Carneiro was at the U.S. Immigration and Customs Enforcement field office in Scarborough for a scheduled check-in on Tuesday when agents detained him without a warrant, according to a petition filed by his attorneys earlier this week.

Carneiro was moved to Burlington, Massachusetts, on Tuesday evening, hours before U.S. District Court Judge Stacey Neumann ordered that ICE not move Carneiro out of Maine, according to the U.S. Attorney’s Office for the District of Maine. The temporary emergency order also barred Carneiro from being moved out of the country.

On Wednesday, Neumann ordered ICE to provide the legal basis for why Carneiro was detained. According to his petition, Carneiro is an Angolan asylum seeker waiting for an immigration court hearing in 2027.

Assistant U.S. Attorney James Concannon didn’t provide details, in a filing Thursday, about why ICE detained Carneiro. Concannon argued that Neumann doesn’t have the authority to rule on Carneiro’s case now that he’s in Massachusetts.

Concannon did not immediately respond to a request for comment Thursday afternoon.

Carneiro had applied for asylum after arriving in the United States in 2023, according to his petition. He has a wife and two children, who are both U.S. citizens, in Maine. Carneiro’s attorneys did not immediately respond to requests for comment Thursday.
