The incident occurred last February, when the fraternity was on probation with the university over issues of hazing and conduct that threatens the health and safety of students.

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.
