MIAMI (AP) — A Canadian man being held by immigration officials in South Florida has died in federal custody, officials said. Johnny Noviello, 49, died Monday afternoon at the Bureau of Prisons Federal Detention Center in Miami, a U.S. Immigration and Customs Enforcement press release said. The cause of death was under investigation.

The death of Johnny Noviello, 49, came as ICE agents have made sweeping arrests across the United States as part of President Trump’s crackdown on immigration. The cause is under investigation.

Canadian consular officials are pressing for more information from the US government after a Canadian citizen died while in the custody of US Immigration and Customs Enforcement in a Florida detention center this week.
