At least two Minnesota university students have been detained by U.S. Immigration and Customs Enforcement in the last week, according to school officials.

Mankato student was detained by ICE last Friday, and university officials say no reason was given about why. University president Edward Inch said in a letter to the campus community that he has been in contact with elected officials to ask for help in stopping this from happening to MSU students.

Students from Minnesota State University Mankato and the University of Minnesota were detained late last week.
