STATE COLLEGE, Pa. -- A Penn State University fraternity was suspended for a year Tuesday after police began investigating allegations that members used a private, invitation-only Facebook page to post photos of nude and partly nude women, some apparently asleep or passed out.
A former member of Kappa Delta Rho at the university's flagship campus in State College tipped police off to the page, telling them in January that it had been used by members to share photos of "unsuspecting victims, drug sales and hazing," according to a copy of a police search warrant.
The ex-member also provided authorities with printouts from the page.
State College Police Assistant Chief John Gardner told CBS News the photos showed "primarily females in various states of undress."
"I don't want to get into numbers, but they were pretty disturbing," Gardner said.
While the fraternity's national organization suspended the Penn State chapter for a year, police and the university said their investigations were continuing and could result in criminal charges, including invasion of privacy and harassment.
"We are looking for any victims, any potential victims, to come forward," Garner said. "We can aid in identification of any perpetrators, that will aid us in the investigation and prosecution of anybody responsible for these despicable acts."
In a letter, the fraternity's national executive director, Joe Rosenberg, told the Penn State chapter it would be banned from most activities for the near future and must reorganize.
He said the suspension was "for the most serious misconduct, most serious disregard of fraternity rules."
Chapter officials, who can appeal the decision, did not respond to messages seeking comment. A young man who answered the door Tuesday afternoon declined to identify himself and said the fraternity had no comment.
A Penn State administrator called the allegations a violation of the standards and values required for recognized student organizations.
"The evidence offered by the Facebook postings is appalling, offensive and inconsistent" with the university's expectations, Damon Sims, Penn State's vice president for student affairs, said in a news release.
Sims said the school would find those responsible and hold them accountable.
State College police said they first fielded the complaint on Jan. 18 and reported the matter to university administrators on March 3.
The informant's computer "yielded information on two victims whose images would rise to the level of criminal action," State College police Lt. Keith Robb said Tuesday.
Facebook was contacted to disable the site and to obtain more information for the investigation, Robb said.
Some of the postings involved nude women in "sexual or embarrassing positions," the warrant reads. "It appears from the photos provided that the individuals in the photos are not aware that the photos had been taken."
Penn State's Interfraternity Council planned a full review of Kappa Delta Rho's conduct.
According to the ex-fraternity member who went to police, a second page dubbed "2.0" was started in about April 2014 after a woman depicted on the first Facebook page, called "Covert Business Transactions," complained.
The informant said the woman was visiting the fraternity when a member accidentally left his Facebook page logged in, and she noticed a topless photograph of her had been posted to the group.
Robb told the AP she wanted the photo removed but did not wish to press charges.
"A lot of that is probably what we're going to end up with, people who don't want anything done, just these photos removed," Robb said. "That's already done."
According to the warrant, the fraternity's page had 144 active members that included both students and alumni.
Penn State's director of student conduct, Danny Shaha, told reporters that students are still living in the fraternity house. He said the house is privately owned, giving the university little control over it.
The photographs accompanying the warrant included images of fully nude and partly clothed women and a scene of a man appearing to grope a woman, her pants partly pulled down.
The informant who visited the police station provided police with brief explanations for individual photos. One, he said, showed a woman vomiting in a member's room. Another showed "the type of stuff that happens at KDR." Two other images showed strippers hired by the fraternity for a party.
Some of the posts included with the warrant were images of cellphone text exchanges, including one from a woman apparently concerned about a casual sexual encounter the night before and whether birth control was used.
