According to the Oregonian, 62-year-old Kenneth Medenbach was arrested in a Safeway parking lot for "unauthorized use of a motor vehicle."
He was already on probation, according to the paper for his ties to an earlier anti-government standoff elsewhere in the state.
The U.S. Fish and Wildlife Service applauded his arrest, according to the Oregonian.
"The U.S. Fish and Wildlife Service is grateful for the quick actions from law enforcement," spokesman Megan Nagel said. "We will continue to work with law enforcement to recover vehicles bought and paid for by the American people to care for their national wildlife refuge."
The paper also reported there was a second vehicle in the Safeway parking lot but the alleged driver had already gone into the grocery store and was not arrested.
