MINNEAPOLIS — A University of Minnesota graduate business student who’s being held by Immigration and Customs Enforcement is suing for his immediate release, saying his arrest violated his rights and he’s been given little explanation for why he’s being held.

The lawsuit filed this week on behalf of Dogukan Günaydin, 28, a Turkish citizen, says two plainclothes federal officers arrested him on the street outside his St. Paul home while he was on his way to class Thursday.

“Dogukan feared he was being kidnapped as a man in a hooded sweatshirt grabbed him and handcuffed him,” according to his petition.

The lawsuit partially comports with a statement issued Monday by the Department of Homeland Security that he was arrested because he had a conviction for drunken driving on his record. The federal agency said he was not detained for any political activity. His petition says Günaydin has attended no protests and has written no politically driven publications.

His attorney, Hannah Brown, did not immediately respond to messages.
