Violence broke out Thursday at the Nakuru-based Rift Valley Institute of Science and Technology ((RVIST) as students demonstrated after it emerged that one of their colleagues had been raped and brutally injured by unknown assailants. The irate students blocked the busy Nakuru-Eldoret highway at the Ngata Bridge section, demanding justice for their assaulted colleague lamenting that most of them had been attacked and robbed of their valuables at the 2KM notorious stretch connecting the institution and the highway. Sylvester Kibet, a student leader, told The Standard they had received reports at 9pm the previous night that a student had been raped at the bridge. He said they rushed there and found the first-year girl writhing in pain and her torn clothes thrown metres away. She was naked and could not speak.
