Officials on Saturday put the leader of Iowa’s largest school district on administrative leave, a day after federal immigration agents detained him because they said he was in the country illegally.

The Des Moines school board voted unanimously to place Superintendent Ian Roberts on paid leave during a three-minute-long special meeting. The board said Roberts was not available to carry out his duties for the 30,000-student district and stated that officials would reassess his status after getting more information.

After the meeting, school board president Jackie Norris read a statement, saying word of Roberts’ detention Friday made for a “jarring day” but noting that board members still didn’t have all the facts.

In a statement on social media, Norris said the school district had “no confirmed information” about why Roberts was detained and the associate superintendent would be stepping in in his place. The school said they had not been told of the “next potential steps” by immigration authorities.

U.S. Immigration and Customs Enforcement said agents detained Roberts because he was in the country illegally, didn’t have authorization to work and was subject to a final removal order issued in 2024. ICE agents stopped Roberts while he was driving a school-issued vehicle, and the agency said he then fled into a wooded area before being apprehended with help from Iowa State Patrol officers.

“I want to be clear, no one here was aware of any citizenship or immigration issues that Dr. Roberts may have been facing,” Norris said. “The accusations ICE had made against Dr. Roberts are very serious, and we are taking them very seriously.”

Norris said Roberts has retained a Des Moines law firm to represent him. Lawyer Alfredo Parrish confirmed his firm was representing Roberts but declined to comment on his case.

Norris also repeated that the district had done a background check on Roberts before he was hired that didn’t indicate any problems and that he signed a form affirming he was a U.S. citizen. A company that aided in the search for a superintendent in 2023 also hired another firm to conduct “comprehensive criminal, credit and background checks” on Roberts that didn’t indicate any citizenship issues, Norris said.

Also Saturday, the Iowa Department of Education released a statement saying Roberts stated he was a U.S. citizen when he applied for an administrator license. The department said the Iowa Board of Educational Examiners conducted a criminal history check with state and federal authorities before issuing a license.

The department said it is reviewing the Des Moines district’s hiring procedures for ensuring people are authorized to work in the U.S.

According to CBS Des Moines affiliate KCCI, the district said Roberts underwent a background check in 2023 by a private contractor, and during the hiring process, he made the board aware of a firearm charge related to a hunting rifle, and provided “sufficient context and explanation” to move forward.

Roberts was licensed by the Iowa Board of Educational Examiners, the district told KCCI.

Roberts had previously said he was born to immigrant parents from Guyana and spent much of his childhood in Brooklyn, New York. He competed in the 2000 Olympics in track and field for Guyana.

ICE said he entered the U.S. on a student visa in 1999.

A former senior Guyanese police official on Saturday remembered Roberts as a middle-distance runner who could have risen through the ranks of the South American country’s police force had he not emigrated to the U.S. decades ago. Retired assistant Guyana Police Force commissioner Paul Slowe said Roberts entered the Police Force after graduating from the country’s standard military officers’ course.

“He served for a few years and then left. He was not dismissed or dishonorably discharged at all; he just moved on,” Slowe told The Associated Press. “He was a good, promising and disciplined man.”
