This is scary video from a high school football game in Pennsylvania, in which one player pulls the helmet off of an opponents head, and then proceeds to hit him with it.

The incident took place during a game between Hamburg High School and Annville-Cleona High School last week.

A Hamburg player took the helmet off the head of an Annville-Cleona player, and then used it to hit him in the head.

Authorities are looking into the incident.
