ICE agents have released a Tomah-based Wisconsin State Patrol trooper from custody.
South African-born Officer Carel Aaron Van Der Merwe was taken into custody this past Thursday in Dunn County.
Van Der Merwe came to the U.S. with his family at the age of 14.
Now age 21, ICE says he has overstayed his visa.
For now, he is required to check in with U.S. Immigration and Customs Enforcement on a periodic basis.
