Police and University at Buffalo officials are looking into a fraternity incident that sent a student to the hospital.
Officials say 18-year-old Sebastian Serafin-Bazan had heart trouble following a possible hazing ritual with the Sigma Pi fraternity.
He's still in critical condition at Buffalo General Medical Center.
The school says it's going to take a closer look at Greek-letter, social fraternal organizations. All official activities by those groups have already been suspended.
