Police had to halt traffic on a highway in North Carolina to help a mother bear get to her cub after it was struck and killed by a vehicle.

Police say the cub was struck Tuesday afternoon and the driver didn't stop.

Officers in the western North Carolina town of Woodfin halted cars for about 20 minutes after the mother bear had failed twice at trying to get her 80-pound cub off the busy highway.

Sgt. Dawn Roberts says officers stood with rifles while others pulled the cub to the side of the road near the mother. She says the mother bear grabbed the cub by the scruff of the neck and ran off into the woods to tend to its body.
