About 30 people were arrested for disorderly conduct during a protest outside the office of Immigration and Customs Enforcement in Bloomington.
The Minnesota Immigration Rights Action group organized the rally Wednesday to protest ICE raids that it says breaks up families.
Bloomington police say the group initially engaged in lawful protests, but several individuals then began blocking driveways and entrances to the building.
Television reports showed them passively resisting officers as they were carried away.
The protest group is calling on President Barack Obama to declare a moratorium on immigration raids and deportations.
Those arrested were released by Wednesday afternoon.
