US authorities have detained right-wing commentator Milo Yiannopoulos and plan to deport him, the Department of Homeland Security said on Friday.

Immigration and Customs Enforcement (ICE) agents arrested the British provocateur at New Orleans International Airport on Thursday for overstaying in the US, the department said, describing him as an "illegal alien from the United Kingdom."

"Yiannopoulos was issued a final order of removal by an Immigration Judge on July 22, after failing to show up for his immigration hearing," the agency said. "He will remain in ICE custody pending removal. "

ICE directed family and legal representatives to contact the agency’s office in Alexandria, Louisiana, which serves as a deportation hub for international flights.

Far-right activist Laura Loomer, who routinely takes credit for action against those who have fallen out with the US president, posted about the incident shortly after.
