Police say four people have been arrested at the site of a planned two-month encampment in southwestern Michigan by an offshoot of the Occupy Wall Street protests.

Kalamazoo Department of Public Safety Assistant Chief Brian Uridge tells the Kalamazoo Gazette that three of the arrests Tuesday at Bronson Park were on previous warrants.

Those involved say police in southwestern Michigan shut down the Occupy Kalamazoo encampment. But Uridge says those remaining at the camp left on their own.

The camp was set up on Monday, in part to address issues of homelessness. Chris Wahmhoff, an Occupy Kalamazoo organizer, says he was arrested for civil disobedience. He and others involved appealed to the Kalamazoo City Commission on Tuesday night.
