The police lathi-charged and used water cannons to disperse student protesters in Ranchi today after they breached the barricades to reach the Jharkhand assembly. This despite Chief Minister Hemant Soren asserting that dialogue, not batons, can solve all problems at home. Their careers plagued by paper leaks and irregularities, the students had announced the assembly siege today to press their demand for reforms in recruitment tests. Student leader Devendra Mahto, who had been on hunger strike, appealed to the protesters not to argue with the police if they are stopped and search for new avenues to reach the assembly in a disciplined manner.
