STATE COLLEGE, Pa. (AP) — The president of Penn State University says a fraternity's Facebook posting of photos of nude and partly nude women is both sad and "very offensive."

Eric Barron tells The Associated Press the behavior is the kind that could get students expelled.

The national leaders of Kappa Delta Rho on Tuesday suspended the Penn State chapter for a year over the photo scandal.

Police in State College are investigating allegations the fraternity operated a private, invitation-only Facebook page in which members shared frat house pictures of women nude or partly nude, some asleep or passed out.

Barron says the university is working with police to determine the number of offenders and victims.

The university is promising to hold accountable all those responsible.
