University of London officials said Friday they had been granted an injunction against protests on campus after 41 students were arrested in two days of unrest. Administrators said they sought the emergency injunction as a final resort to curb what they called "a campaign of aggression and intimidation." The protests are part of a wave of sit-ins at colleges across England in opposition to plans to privatize university support services. Rosie Holland, 20, a mathematics major who helped organize the protests, charged the university was "taking our space away." "And we don't like the way education is being run, the commercialization, the privatization of it," she said. "This is an education system that needs to change." The injunction, which bans protests on campus until June 2014, was granted by the High Court after violent clashes Wednesday between police and more than 200 students. A university spokesman said some protesters were seen covering their faces and carrying homemade shields during the confrontation. Smoke bombs and other objects were thrown at police. Thirty-six people were arrested Thursday in altercations during a sit-in at a campus building.
