MILL HALL, Pa. - Authorities say a bear attacked a teenager in central Pennsylvania as she hunted deer on a family farm.

State police say the 18-year-old girl from Mill Hall suffered severe bites on her arms and shoulders, and a deep cut on her head.

Authorities say the teen was hunting in Porter Township with a large group on Monday when three black bear cubs ran past her.

Troopers say the girl turned around to see a large black bear charging her. As the animal began attacking, police say the victim's stepfather was able to scare it off.

The girl underwent surgery at a local hospital. The Pennsylvania Game Commission is investigating.
