The Enforcement Directorate has arrested former TMC MP K D Singh in connection with a money laundering case, reports said on Wednesday. Singh has been placed under arrest under various sections of the Prevention of Money Laundering Act. The central probe agency had carried out searches at Singh's residence and that of his aides in September 2019 in connection with two PMLA cases. Singh has been the chairman of the Alchemist Group and resigned from the post in 2012, but he is stated to be the Chairman, Emeritus and founder of the business group. The scam is stated to be about ₹1,900 crore and the ED had attached assets worth Rs 239 crore of Alchemist Infra Realty Ltd earlier this year. The Trinamool Congress led by West Bengal Chief Minister Mamata Banerjee has maintained that KD Singh has not been involved in party affairs for quite some time.
