BATON ROUGE - An LSU sorority's events are being put on hold as authorities investigate possible hazing allegations.

According to the sorority's national chapter, Pi Beta Phi is under investigation for events that "may have constituted hazing." Few details were made available Thursday, but the chapter said the allegations did not involve alcohol, and no one was physically harmed.

A spokesperson went on to say the LSU chapter reported the incidents to local law enforcement and is cooperating with the investigation. 

All of the sorority's activities have been halted while the allegations are looked into. According to LSU, "the university has entered its investigative process."

It's the third Greek organization investigated at LSU since August, when Delta Chi was suspended over an incident that allegedly violated the school's code of conduct. Pi Kappa Phi, another fraternity, was suspended in October over what the university called "very serious" allegations.
