Four members of Kappa Alpha Psi fraternity have been charged with hazing several students at California State University.

According to reports, police began an investigation into a report of a felonious assault during fraternity pledge initiations.

The report was initiated through Mercy Hospital when a 25-year-old man was admitted to the hospital as a result of his injuries.

The investigation revealed that between March 28 and April 25, four CSUB students were assaulted multiple times during numerous initiation ceremonies, during which they were beaten and shot at close range with a BB pistol, DeGeare said.

Four of the group’s members have been arrested.
