In a pre-dawn swoop today, the National Investigation Agency (NIA) arrested Trinamool Congress State Committee member Chhatradhar Mahato from his home in Jhargram district's Lalgarh and whisked him off to Kolkata to be produced before a court around noon. He was asleep when a 40-member team dragged him away, local sources said. A policeman was injured during the incident. The 57-year-old Mr Mahato's family refused to sign or accept any document served by the agency.
