Students from the Nelson Mandela University have barricaded entrances to the two Summerstrand campuses in Port Elizabeth, calling for stringent security measures on all campuses. This comes after two students were attacked at the Computer lab on the University's 2nd Avenue campus. One student was allegedly raped and another stabbed. The students are calling for better shuttle services, more security personnel and police visibility especially after hours. Olwethu Matsipane reports
