ST. PAUL, MN (AP) -

The Minnesota Department of Natural Resources says it's investigating a rare apparent wolf attack on a teenager.

The DNR says it happened early Saturday morning at the West Winnie Campground on Lake Winnibigoshish in north-central Minnesota.

It says the 16-year-old boy suffered multiple puncture wounds and a laceration on his head about 4 inches long. The wolf ran into the woods after the boy kicked it.

After receiving local first aid, the boy was taken to a Bemidji hospital. The wound required multiple staples to close, but was not life-threatening.

The DNR says a serious injury or fatal attack on a human had never been documented in Minnesota before. The only two recorded wolf attack fatalities in North America in the last decade were in northern Canada and Alaska.
