U.S. Immigration and Customs Enforcement agents arrested a graduate student attending the University of Minnesota earlier this week, the school said Friday in a statement that called the situation “deeply concerning.”

The student was taken into custody on Thursday at an off-campus residence, the school’s president, Rebecca Cunningham, said in the statement.

“The university had no prior knowledge of this incident and did not share any information with federal authorities before it occurred,” the statement said.

The university did not identify the student’s name, nationality or visa type. Jake Ricker, a university spokesman, said the student was enrolled in the Carlson School of Management.

ICE officials did not immediately respond to a request for information about the case.

The arrest follows other incidents in which ICE targeted international students or scholars at American universities. Three involved students at Columbia University. The other individuals ICE detained or sought to arrest attended Brown, Tufts, Cornell and the University of Alabama.

Another case that drew consternation among civil liberties advocates involved Mahmoud Khalil, a permanent U.S. resident and recent graduate at Columbia University who had his green card revoked.
