Penn State's president says some senior university leaders believe their fraternity system needs to be re-evaluated following a police investigation into the Facebook posting of nude photographs of women by a now-suspended fraternity.

Eric Barron told faculty, staff and students in a statement sent on Wednesday night that some leaders believe there is a need for such a review.

He says the university is working with the national leadership of Kappa Delta Rho, which this week suspended its Penn State chapter for a year, to see if it "will have a presence" on campus.

Police are investigating allegations the fraternity operated a private Facebook page on which members shared frat house pictures of nude and semi-nude women, some of whom appeared to be asleep or passed out.
