The Enforcement Directorate (ED) on Tuesday conducted searches at several premises across Kolkata in connection with alleged financial dealings, unlawful collection of money and routing of suspected funds through certain bank accounts of the Trinamool Congress (TMC).Searches were conducted at five premises of Carewell Group operating in the aviation sector. It has been revealed that around Rs 160 crore were reportedly transferred from the TMC accounts to M/s Carewell Aviation India Pvt Ltd and its related entity, tentatively between April 2023 and June 2026.M/s Carewell Aviation Pvt Ltd allegedly further routed an amount of Rs 82.96 crore between 2023 and 2026 to another newly incorporated related entity, the ED sources informed.Further, a significant amount reportedly travelled to a related entity of M/s Carewell Aviation India Pvt Ltd for purchasing an Embrarer Legacy 600 aircraft and Augusta 109 SP chopper.An amount of Rs 112 crore was reportedly used for making the said purchases, sources informed.The probe found that that some foreign funding was also utilised for making the purchase of the Agusta chopper. However, most of the funds have allegedly been sourced directly from the accounts of the TMC.These Embraer Legacy 600 aircraft and Agusta helicopter were reportedly rented out to the AITC itself, even though they were purchased from the corpus of the TMC.Thereafter, substantial amounts were reportedly transferred on the pretext of aircraft usage.The entire arrangement appears highly doubtful and seems designed to camouflage the actual beneficial purpose of the transactions, which is presently under investigation, the ED official said.
