A Wisconsin state trooper has been detained by Immigration and Customs Enforcement and is facing deportation to South Africa, according to his lawyer.

Aaron Van Der Merwe, 21, was detained Thursday as he was waiting to board a domestic flight, according to a statement issued by law firm Christopher & De León.

Van Der Merwe told ICE officers he had a work permit and a pending asylum application.

“According to Van Der Merwe, the officers said they did not care, placed him in handcuffs and shackles, and transported him to immigration detention in Dodge County,” the law firm said.

An ICE database shows Van Der Merwe is currently being held at a detention facility in Juneau, Wisconsin.
