A polar bear killed a man out for a stroll with his girlfriend in an unprovoked attack in a remote northwest Alaska village in the first such attack in recent memory, federal officials said.

The bear dragged the man's body away, and a search party followed a trail of blood and tracks for about an hour until they found the bear sleeping by the partially eaten body. The bear was shot and killed by a Point Lay teacher."We have not seen a fatal encounter with a polar bear in modern times in the Alaska arctic," U.S. Fish and Wildlife Service spokesman Bruce Batten said Sunday in Anchorage.
