A Daily Herald Media report says the bear was discovered early Saturday in an employee parking garage.
Marathon County sheriff's Lt. Mark Wagers says an animal-control officer subdued the animal with a drugged dart. Officials with the state Department of Natural Resources took it to a wooded area and released it.
Wagers says the bear was an unusual sight, but deputies weren't fazed. He says they've had to deal with a variety of animals that get trapped in the garage somehow, including deer and owls.
