A former UC Berkeley student accused university football players and athletics staff of sexually harassing her when she worked for the team’s sports medicine unit on Wednesday.

The university has not confirmed whether it will investigate the woman’s allegations.

“We are aware of the very disturbing public allegations made on social media,” Cal Athletics said in a statement. “These allegations go against the very core of our values.

Last March, investigators with the U.S. Department of Education’s Office for Civil Rights found that UC Berkeley was out of compliance with Title IX, the law prohibiting sexual discrimination at schools receiving federal funding.

Since April 2011, the U.S. government has opened 502 investigations into colleges for potentially mishandling sexual misconduct reports, according to the Chronicle of Higher Education, which tracks the cases.

Authorities have opened and resolved two cases at Berkeley in that time.

Officials studied sexual misconduct complaints filed with the university from 2011 through 2014, and some cases from 2017. The office ordered the university to revise eight sexual misconduct cases it may have mishandled and improve campus policies for teaching students and staff about sexual abuse.

A state audit released three months later echoed concerns about adequate and timely responses to sexual harassment complaints throughout the UC system.

The school has received 540 allegations of sexual harassment since the beginning of 2016, according to university data.

Here are the outcomes of some recent sexual harassment cases and investigations against involving Cal employees:

• Former UC Berkeley Chancellor Nicholas Dirks fired Blake Wentworth, an assistant professor of South and Southeast Asian studies, in May 2017 after the university upheld complaints he sexually harassed and inappropriately touched a graduate student.

• A Cal alumna filed a lawsuit against a philosophy professor and the UC regents in March 2017 claiming he groped and sexually harassed her while working as his research assistant. The student, Joanna Ong, said she tried to report professor John Searle’s misconduct to the director of the research center when it happened in 2014, but they did not take the case to university adminsitration.

• Cal basketball assistant coach Yann Hufnagel resigned in April 2016 after an seven-month investigation found he had sexually harassed a female reporter in 2014 and 2015. The case also raised questions about whether former head coach Cuonzo Martin was aware of the ccusations. Martin quit in March 2017 to take a coaching job at Missourri.

• Layshia Clarendon, a former Cal women’s basketball player, sued the university’s regents in January 2018 in an Alameda County court, alleging negligence when an athletics department employee assaulted her at his home when she was a freshman. Cal fired Mohamed Muqtar in May following the inquiry.

• In February, the university suspended a prominent East Asian languages and cultures professor for two years after he sexually harassed a student and created a hostile work environment for her. Alan Tansman also allegedly harassed or flirted with several other women, according to findings by a campus investigator.

• An architecture professor resigned in September 2018 amid allegations that he sexually harassed a graduate student. A month prior, UC Berkeley suspended Nezar AlSayyad for three years without pay after he “engaged in a pattern of sexual harassment that created a hostile environment.” the university’s vice provost said to the student. AlSayyad sued the school in October.
