A Guatemalan deportee, who the Trump administration was in the process of facilitating a return to the U.S. following a court mandate, arrived on American soil on Wednesday, according to his lawyers.

Identified as O.C.G. in court papers, he flew on a commercial plane to California, communicating with his legal representatives while queuing for U.S. Customs and Border Protection, explained Trina Realmuto from the National Immigration Litigation Alliance.

Subsequently, U.S. Immigration and Customs Enforcement detained him, with plans to transfer him to a detention center in Arizona, Realmuto mentioned in an email to The Associated Press.

The Trump administration said in court filings last month that it was working to bring him back after he was deported to Mexico, despite his fears of being harmed there, days after a federal judge ordered the administration to facilitate his return.

The U.S. Department of Justice didn’t immediately respond to a request for comments and details from the AP.

The man, who is gay, was protected from being returned to his home country under a U.S. immigration judge’s order at the time. But the U.S. put him on a bus and sent him to Mexico instead, a removal that U.S. District Judge Brian Murphy found likely “lacked any semblance of due process.”

Mexico later returned him to Guatemala, where he was in hiding, according to court documents.

In a court filing before his return, government lawyers said that a so-called significant public benefit parole packet had been approved. The designation allows people who aren’t eligible to enter the U.S. to do so temporarily, often for reasons related to law enforcement or legal proceedings.

An earlier court proceeding had determined that the man risked persecution or torture if returned to Guatemala. But he also feared returning to Mexico, where he says he was raped and extorted while seeking asylum in the U.S., according to court documents.

“As far as we know, it is the first time since January 20 that (Department of Homeland Security) has facilitated return following a district court order,” Realmuto said.

The case is among a string of findings by federal courts against recent Trump administration deportations. Those have included other deportations to third countries and the erroneous deportation of Kilmar Abrego Garcia, an El Salvadoran man who had lived in Maryland for roughly 14 years.

The U.S. Supreme Court ordered the Trump administration to facilitate Abrego Garcia’s return to the U.S. from a notorious Salvadoran prison, rejecting the White House’s claim that it couldn’t retrieve him after mistakenly deporting him. Both the White House and the El Salvadoran president have said they are powerless to return him.
