DES MOINES, Iowa (AP) — Lawyers for the leader of the Des Moines public schools, Superintendent Ian Roberts, have filed a request with a federal immigration court in Omaha to halt deportation proceedings against him. Attorney Alfredo Parrish stated that the filing was made under seal, with further details expected to be revealed at a scheduled news conference later. Roberts, originally from Guyana, was detained by U.S. Immigration and Customs Enforcement (ICE) last week, accused of living and working illegally in the U.S. Following his detention, the Des Moines school board promptly revoked his superintendent's license and voted to place him on unpaid leave from his role leading the district, which serves over 30,000 students. Board chair Jackie Norris indicated that Roberts and his legal representatives must provide documentation proving his eligibility to work in the U.S. by noon Tuesday, or face further dismissal proceedings. Roberts, aged 54, has been incarcerated since his arrest at the Woodbury County Jail in Sioux City, Iowa, approximately 150 miles from Des Moines.
