CHANDIGARH: Over 50 people, including students, police personnel and journalists were injured as students, protesting massive fee hike for different courses, clashed with the police on the Punjab University campus last week. Authorities took over 50 students into custody, slapping sedition charges on all those indulging in violence. Police resorted to baton charge, use of water cannons and tear-gas to disperse the agitators who had gathered near the Vice Chancellor's Office complex. On the other hand, protesters pelted stones at the police and broke window panes and flower pots. The hike was being opposed by student organisations, including Panjab University Students Union, Students of Panjab University, and Students Organisation of India.
