Columbia, Mo., police are investigating an incident that led the University of Missouri-Columbia to temporarily suspend a fraternity Monday.

Mizzou officials were mum about what happened during “a hazing incident” involving the Kappa Alpha fraternity.

According to Columbia police, an assault was reported Thursday at the fraternity house at 1301 University Avenue “for a subject from the house drinking to the point of being transported by ambulance to a local hospital.”

The subject was 18 years old, police said. The drinking happened about 11 p.m. Tuesday, and the subject was taken to the hospital about 10:30 a.m. the next day.

Officer Latisha Stroer from the Columbia Police Department said the subject’s condition was unknown. She couldn’t say who reported the incident.

“On Thursday, Kappa Alpha Order temporarily suspended our chapter at the University of Missouri to investigate an alcohol incident, and allegations of hazing,” the group said in a statement. “Misuse of alcohol, and hazing, are each contrary to our values and are strictly and expressly prohibited by Kappa Alpha Order. We are in close cooperation with the University in this situation.”
