Colorado Wildlife Officials are looking for an aggressive bear that was not discouraged by pepper spray, car horns and gunshots at Chambers Lake Campground.

The Denver Channel is reporting that the bear was swiping at a tent and knocked a cooler off a truck early Saturday morning causing a camper to fire warning shots to scare it away.

Campground visitors say that the bear then returned that evening causing campers to honk car horns and use pepper spray.

Wildlife officials say if a bear has lost it's fear of humans, they can be extremely dangerous and aggressive.

Official Warning from U.S. Forest Service:
