Some Texas Tech University students have demonstrated against what they say is a "rape culture" on campus by laying bed sheets spray-painted with "no means no" at three locations.
The women's actions Wednesday came a day after university officials sent an email to students and faculty that called activities at a recent off-campus fraternity party "reprehensible."
A picture of a banner at the Sept. 20 Phi Delta Theta fraternity gathering, briefly posted online, read, "No means yes, yes means anal (sex)."
University spokesman Chris Cook said the school learned of the banner the day after the party and began investigating immediately. Last week the university established a task force to review Greek organizations.
The latest news from around North Texas.
The bed sheets displayed Wednesday were removed by police after about 30 minutes.
