The U.S. Immigration and Customs Enforcement (ICE) is reporting they’ve arrested 83 people in Wisconsin over the course of a four-day operation.

Out of those arrests, nine were found in Brown County, while four were in Kewaunee, three in Outagamie, two in Door, and one in Oconto Counties. The people arrested were from eight countries, including Colombia, Guatemala, Honduras, Mexico, Nicaragua, Russia, Thailand and Vietnam. Of those arrested, 77 were men and six were women.

According to ICE, 44 of those arrested have criminal convictions on their record while 21 of them are believed to have also been previously deported from the country. 

Over the weekend, officials in the City of Madison protested the recent arrests, with Madison Police Chief Mike Koval even saying that ICE did not follow proper procedures and didn’t notify his department of the arrests. ICE reported that they arrested 20 people in Dane County, which is where Madison is located.
