Rochester, MN (KROC AM News) - Rochester police arrested several people Wednesday after a confrontation that happened during an overnight party that was still going on at six in the morning.

Officers were sent to an apartment building in the 2600 block of 4th Ave NE to check on a 911 hangup call. They found a large party in one apartment - and a woman in her underwear knocking on the door of another unit. They discovered the woman’s estranged boyfriend was inside and had assaulted her. He had also been ordered by a judge to have no contact with the woman.

The man resisted when the officers tried to arrest him. Several people at the party saw what was going on and confronted the officers, who used pepper spray to break up the crowd. They eventually arrested five other people.
