New Delhi, April 22 -- As the campaign for the phase-1 of the crucial West Benal assembly elections came to a close on Tuesday evening, a spate of actions by the Enforcement Directorate (ED) against members of the ruling Trinamool Congress (TMC) are in focus. Polling in the first phase will be conducted on Thursday, with the second phase scheduled for April 29. As the political temperature rose in the state in the run up to the polls, ED has launched a flurry of actions including high-profile raids, arrests, attachment of properties, filing of charge sheets and summoning of people directly or indirectly linked to the TMC, people familiar with the developments said. In the past one month alone, according to details compiled by HT, the agency has mounted over a dozen operations, with officials terming the crackdown crucial to unearth financial irregularities. The most prominent action has been on the Indian-Political Action Committee or I-PAC -, which was first raided on April 2 in a fresh case related to its unaccounted funding followed by the arrest of its director Vinesh Chandel on April 13. The agency has alleged that it has detected proceeds of crime worth Rs 50 crore linked to I-PAC so far. The federal agency also issued summons last week to I-PAC's another director Pratik Jain's wife, Barbie, and brother Pulkit. On April 14, the agency also attached assets worth Rs 159 crore in its separate probe related to the alleged coal mining in West Bengal, in which I-PAC was raided in January this year. I-PAC works with the TMC and the latter has claimed that a conspiracy was being orchestrated by the Bharatiya Janata Party (BJP) led centre to cripple its campaign through intimidation. Another high-profile ED action was seen in West Bengal on April 19, when the agency sleuths launched raids at the residence of Kolkata police Deputy Commissioner of Police (DCP) - Shantanu Sinha Biswas - and businessman, Joy Kamdar (managing director of Sun Enterprise) in a money laundering case pertaining to various criminal activities such as extortion, grabbing of real estate properties, and unauthorized construction. Kamdar was arrested the same day while summons were issued to Biswas. The DCP is under ED scanner in two other cases, including a case pertaining to alleged fake NRI quota admissions in private medical colleges in West Bengal. In the Joy Kamdar related probe, ED had also issued summons to Gaurav Lal, IPS, Joint Commissioner of Police, Howrah Police Commissionerate on April 13. The federal agency has also, on April 22, summoned Bengali actor and former TMC member of Parliament Nusrat Jahan in connection with its probe into siphoning of PDS ration in the state. On Tuesday, a summon was issued to the former principal secretary (education) of West Bengal, Manish Jain, as well in connection with the irregularities in the assistant teacher recruitment. Former minister Partha Chatterjee was also raided on April 11 in this case. Last week, the financial crimes probe agency also raided a Kolkata based real estate firm Merlin Group, promoted by Sushil Mohta and Saket Mohta. It is alleged that the accused persons fabricated and forged documents and fraudulently grabbed various parcels of land including public land too in the state. An officer, who didn't want to be named, said "all of its action is in ongoing probes and has been taken by following due process". However, the ruling party in the state has said that BJP was using the investigative agencies ahead of the assembly elections. Congress leader KC Venugopal said on Tuesday that "the BJP will try to make a non-issue become an issue... Prime Minister Modi is trying to terrorise people by using ED, CBI. That's what Mallikarjun Kharge said. You also know all these camera tricks"....
