At least two Minnesota university students have been detained by U.S. Immigration and Customs Enforcement in the last week, according to school officials. In a statement released Monday, the president of Minnesota State University-Mankato said a student was detained by ICE at an off-campus residence last Friday.

President Edward Inch notified students and faculty with a campus-wide email about the detainment on Monday afternoon. No reasons were given for the student’s detainment.

The recent arrests of college students in Mankato and Minneapolis come as several foreign nationals affiliated with American universities have found themselves targets of the Trump administration’s immigration crackdown.
