U.S. Immigration and Customs Enforcement agents attempted entry into a Chicago elementary school Friday morning, but were not allowed inside or permitted to speak to anyone inside, Chicago Public Schools officials said.

U.S. Immigration and Customs Enforcement agents were seen at a Chicago school Friday afternoon, hours after a Trump administration official confirmed that Illinois was among several states where hundreds of arrests had previously been made.

According to the school's principal, Natasha Ortega, agents were not allowed entry or permitted to speak with students or staff.

However, a spokesman for Immigration and Customs Enforcement said it was not their agency that attempted to enter the school.
