The bandh called by the Popular Front of India (PFI) in Kerala against the pre-dawn raids and arrest of its key leaders by central agencies turned violent on Friday. Several incidents of vandalism and violence have been reported across the state and stones were pelted in various districts such as Thiruvananthapuram, Kollam, Kozhikode, Wayanad and Alappuzha. After the protests turned violent, the Kerala High Court initiated a suo motu cognisance against the leaders of PFI, calling flash hartal in the state which was earlier banned by the court. The court observed immediate action should be taken against ongoing attacks. Flash hartals means, harthals that are called without giving a prior notice. So Kerala HC has said harthals should be called after giving at least seven days' prior notice.
