GRAND CHUTE - A motorist driving Monday morning on Interstate 41 reported an unusual sight: a kangaroo hopping across a walking bridge over the busy stretch of highway.

The kangaroo was supposedly seen crossing the walking bridge heading east from Fox Cities Stadium, according to Grand Chute community resource officer Travis Waas.

A single caller reported the kangaroo sighting shortly before 7 a.m. Officers responded to the area, but were "unable to locate any marsupials," Waas said.

But if officers had found a kangaroo, they would have tried to contain the animal, then would have contacted zoos in the region for help trapping, moving and finding the animal's owner, Waas said.

A kangaroo sighting isn't without precedent in northeast Wisconsin. In November, a young kangaroo named Lulu escaped from a home in Shawano County and was hit and killed by a pickup truck.
