Athens, Ohio- from www.cbsnews.com – Pi Beta Phi, a national sorority suspended for misconduct at Miami University in Oxford, Ohio, now has a second chapter in the state accused of destructive behavior at a formal, including allegations of a bathroom sex romp.

An attorney for the Parkersburg Art Center in West Virginia says the gallery sustained $46,555 in damage, when Ohio University’s Pi Beta Phi chapter held its winter formal March 6. Lawyer Richard Hayhurst says food was thrown around, drinks were dumped on floors, and a sink was pulled from a wall when a couple tried to have sex on it.

An angry letter, obtained by Deadspin, was addressed to Pi Beta Phi Chapter President Anne Duffy [pictured].

However, the Ohio University sorority chapter says the gallery that hosted the event is making “grossly exaggerated” claims.

Pi Beta Phi maintains in a statement that the only problem that occurred was that beer taps were taken from the art center.

Ohio University said Monday it’s investigating the allegations.
