Penn State University and the national Kappa Delta Rho fraternity have suspended the KDR chapter at the university after allegations surfaced the members had posted photos on a private Facebook group of unconscious naked women as well as other illegal activity.

CNN reports State College police began investigating the KDR chapter at Penn State after a former member approached police with screenshots of the group that showed photos of nude and semi-nude women, interactions about illicit drug purchases, and conversations with women who did not recall sexual encounters.

The private Facebook group had 144 members comprised of current students and alumni. However, the informant told police the chapter had formed a second group in April 2014 called "2.0" after a woman found photos of herself on the first group titled "Covert Business Transactions."

"No arrests are being made at this time," State College Police Lt. Keith Robb said. "Unfortunately, we aren't able to identify any suspects right now because the accounts on Facebook were sanitized, wiped clean."

However, the investigation continues. Penn State released an announcement saying the chapter had been suspended.

"This action is being taken in response to the chapter allegedly hosting private Facebook pages where highly inappropriate photographs were posted of activities and events that are in direct violation of the standards and values of a recognized student organization at Penn State," wrote Damon Sims, Penn State Vice President for Student Affairs.

"The evidence offered by the Facebook postings is appalling, offensive and inconsistent with the University community's values and expectations."

The national KDR organization also released a statement on Facebook announcing it would begin its own investigation into the chapter, suspending it for a year and ordering a full membership review and reorganization.

Executive Director Joseph Rosenberg explained the national organization will cooperate with police and the university in the investigation.

"Upon the completion of that investigation, we will evaluate these further findings and make a decision regarding the Penn State chapter that is appropriate for all parties," he added. "The national leadership of Kappa Delta Rho is committed to hold our brothers accountable for their actions. We embrace the principle of respect for all persons and we will adhere to that principle in this matter."

According to Pittsburgh Post-Gazette, police are exploring criminal charges against those who may be involved.

"First of all, we're looking at an invasion of privacy, which is a misdemeanor charge," said State College Assistant Police Chief John Gardner. "We can also be looking at harassment, which could be a summary or a misdemeanor level. We're going to explore every and all options."

The affidavit, according to CNN, mentions photos of "unsuspecting victims, drug sales and hazing" appeared online. The drug allegations concern "marijuana and edibles, concentrates, ADD medication, and some cocaine."
