A 5-year-old boy from Minnesota has fallen ill while detained with his father at an Immigration and Customs Enforcement facility in Texas, with family members and school officials expressing alarm over his deteriorating condition, PEOPLE reports.

Liam Conejo Ramos and his father, Adrian Conejo Arias, are being held at the South Texas Family Residential Center in Dilley, Texas, following their detention earlier this month, according to PEOPLE. The boy’s mother, Erika Ramos, told Minnesota Public Radio on Monday that her son is experiencing stomach pain, vomiting, and fever.

“Liam is getting sick because the food they receive is not of good quality. He has stomach pain, he’s vomiting, he has a fever, and he no longer wants to eat,” Ramos said, describing the situation as “deeply concerning.”

Zena Stenvik, superintendent for Columbia Heights Public Schools District where Liam attends, characterized the mother as “incredibly distraught” in an interview with the Huffington Post.

“Unfortunately, Liam’s health is not doing great right now,” Stenvik said. “He’s been ill. I’ve been told he has a fever. So I’m very, very concerned about his well-being in that facility.”
