Masked men and miscreants went on a rampage in different parts of Kerala on Friday during the dawn-to-dusk hartal called by the Popular Front of India (PFI), damaging buses and ambulance, injuring policemen and commoners and vandalising shops and threatening the public.

The PFI called the hartal to protest the raids in the offices and residences of its leaders and their subsequent arrests on Thursday by the National Investigation Agency (NIA) and other agencies for allegedly supporting terror activities in the country.
