Chandigarh, Nov. 11 -- Amid complete pandemonium on the PU campus, police picked up around 70-80 protesters and took them to the India Reserve Battalion (IRB) Complex in Sarangpur. Police clarified that they were not technically detained but shifted from the protest site to maintain order. Nearly 2,000 police personnel had been deployed since 5.30 am, with the entire campus sealed and barricaded from all sides. However, despite the security, protestors forced open the gates, breaking locks and overpowering the police to enter the university premises. As students pushed through, chaos ensued and four policemen - DSP SPS Sondhi, inspector Rohit Kumar, SI Pratibha and senior constable Vipin - sustained injuries . A stampede-like situation unfolded near the gates as protesters surged ahead, shouting slogans and pulling down barricades. Inspector General (IG) Pushpendra Kumar later said, "It was a deliberate and thoughtful decision to allow the protesters to enter the campus, as our motive was to avoid violence. The demonstration was a success as no untoward incident was reported, and the purpose of the protesters was served. Initially, we did restrain them, but only to allow them later on. This is an emotive issue, and we did not want to use force inside the campus. Upon allegations of senior officers being escorted out, we had merely moved to review arrangements. No force was used."...
