U.S. Customs and Border Protection have confirmed that an 8-year-old Guatemalan child died Tuesday while in their custody.
Once agents noticed the child showing symptoms of illness Monday, "the father and his son were promptly transferred to the Gerald Champion Regional Medical Center", according to a CBP statement.
Officials said the boy, who was in CBP custody, started showing signs of "a potential illness" on December 24.
Monday night, officials said the boy began vomiting and was taken back to the medical center, where officials say he died shortly after midnight Tuesday. The Department of Homeland Security Office of the Inspector General and appropriate members of Congress have also been notified.
A CBP spokesman declined to elaborate, but said more details would be released shortly.
