Colorado ? A man was attacked by a large black bear in his Aspen home in the latest in a string of violent encounters with the animals this summer in the mountain community.

Colorado Division of Wildlife spokesman Randy Hampton said the man had gone to the first floor of his home to check on his three barking dogs when the bear struck him in the head.

Hampton said the man did not suffer life-threatening injuries and was being treated at a local hospital.

Hampton said it’s unknown how the bear entered the home.

Wildlife officers are searching for the bear in the neighborhood and have set up a trap in the area. The bear will be euthanized when it is found.

Wildlife officers in and near the resort town about 200 miles west of Denver have killed at least nine bears so far this summer because of their aggressive behavior. Area police have responded to about 200 bear sightings in August, up from 16 last August.
