A "skit" at a fraternity party that left a pledge with burns over 16% of his body led to authorities filing charges against four San Diego State University students, including the person who was injured.

Four members of a San Diego State fraternity allegedly gave a pledge third-degree burns as part of a hazing ritual that left the young man in the hospital for weeks.

Four San Diego State University fraternity members pleaded not guilty Monday to criminal charges stemming from a skit that allegedly involved intentionally setting one of the defendants on fire, causing him to suffer third-degree burns.
