Polar bear flees its zoo pen in Duluth, escaping the flood.

There was some heavy rain up at Lake Superior today.

“Even though it’s a large white object, it’s pretty nerve racking,” police spokesman Jim Hansen said of the chase for Berlin [the polar bear]. Zoo officials said she was tranquilized by the zoo’s vet and placed in quarantine....

Two seals managed to swim out of the zoo but were quickly recaptured just outside. Wolniakowski said no dangerous animals left the zoo grounds and that all have been secured.
