The Johns Hopkins University has come under fire for not disclosing to the campus an alleged rape at a fraternity house, leading a group of students to file a complaint with the U.S. Department of Education and others to stage a protest Friday.

Amid the pressure, President Ronald J. Daniels said Friday that the university would immediately begin an independent review of how the case was handled, and officials pledged "scrupulous self-examination." Officials also defended their commitment to campus safety.

In the federal complaint, the students allege that failure to disclose the reported rape violates the Clery Act and Title IX, federal laws that dictate how serious crimes like sexual assault should be handled by universities and reported to the public.

The students, who are anonymous in the complaint but represented by the Washington-based advocacy group SurvJustice, urge the federal government to investigate the university's handling of sexual assault in general, arguing that other cases have been bungled.

The incident comes to light in the same week that an Obama administration task force released a report intended to pressure U.S. colleges to do more to combat sexual assault. Also this week, it was revealed that Frostburg State University was under federal investigation for its handling of another alleged rape.

"The university cares about its image of safety, rather than the actual safety of its students," said Mats Dreyer, a Hopkins senior who organized the protest of about 40 students Friday. "A lot of students don't feel safe because they don't feel like they have the information they need to make decisions about their safety."

The students gathered to protest what they say is a culture of silence when it comes to Hopkins holding its own students accountable and taking sexual assault seriously, chanting "Respect over reputation" and "Let us see transparency."

The alleged rape was reported to police in March 2013 in the 3200 block of N. Charles St., at the off-campus, privately owned Pi Kappa Alpha fraternity house named in the federal complaint.

The alleged victim, a Towson University student, went to a hospital for a rape examination and was interviewed by police there, according to a police report. She told officers she had a series of consensual sexual encounters with three men at a fraternity party, at least some of whom were Hopkins students, according to the report. Later, one of the men forced her into non-consensual acts, and two other men joined in, she told police.

"We concluded that there was insufficient evidence to support criminal charges," said Mark Cheshire, a spokesman for the Baltimore state's attorney's office, who declined to provide a more detailed explanation "to respect the privacy of those involved."

Representatives from the Hopkins chapter of Pi Kappa Alpha and its national office did not respond to requests for comment.

Jane Glickman, an Education Department spokeswoman, confirmed that officials had received the Clery Act complaint. The Education Department's Office of Civil Rights has not yet opened a formal investigation into the complaint. Officials don't comment on Title IX complaints.

The Clery Act requires colleges to keep records on and disclose to the public serious crimes that happen on or immediately adjacent to campus property. Title IX, in addition to ensuring gender equity in athletics, also lays out requirements for how universities must handle reports of sexual assault.

The Hopkins complaint filed by SurvJustice contains a lengthy email thread between Hopkins officials. In the emails, the officials debate whether the reported rape allegation by the Towson student at the Pi Kappa Alpha house is subject to the Clery Act's "timely warning" requirement, which obligates universities to warn the community within 90 days about serious or ongoing threats to public safety.

One university official sent an email in June 2013 about growing concerns over the school's obligations under federal law, noting that a group of students were advocating to shut down the fraternity house. The official proposed language to notify the university community of the alleged rape but noted it could draw negative attention to the university, according to a copy of the email in the federal complaint.

Dennis O'Shea, Hopkins' spokesman, asked in an email whether the university needed to send the alert before it got an update on the case from prosecutors.

"The situation could either become clear or change radically at that point," he wrote. "I would hate to have waited so long to say something, then say it, and then have the situation evolve quickly, requiring us quickly to say something different."

Hopkins officials declined to answer questions about the case or the complaint but released a statement. O'Shea did not respond to questions about the emails in the complaint.

"The decision not to notify the university community in that case was made after considering relevant facts and legal requirements, and in consultation with the Baltimore police department, which was leading the investigation," university officials said in the statement. "The Johns Hopkins University is deeply committed to the safety and welfare of our community and to ensuring a safe environment for learning and scholarship.

"That commitment includes protecting our students from sexual violence, offering support to victims, dealing firmly and fairly with alleged offenders, and informing students, faculty and staff of serious and ongoing threats to campus safety. For some time, the university has been directly engaged in a comprehensive effort to address students' concerns about campus sexual assault."
