(AP) — Indiana University said Thursday it has suspended the local chapter of the Alpha Tau Omega fraternity while it investigates a video purportedly showing a pledge performing a sex act on a woman during an apparent hazing ritual. The university said the recording that surfaced on social media "appears to be credible video evidence" of the hazing allegations. In June, the Indiana State University in Terre Haute suspended the fraternity for violations including providing alcohol to minors, hosting unauthorized events and tampering with fire-suppression equipment.
