The Enforcement Directorate has been carrying out raids since early Saturday at multiple properties, allegedly linked to TMC MLA Madan Mitra, in West Bengal as part of its money laundering investigation into municipality recruitment "irregularities", officials said. A total of seven premises allegedly linked to Mitra, a former minister in the previous TMC regime, are being searched, they said. Search operations were launched at Mitra's Bhabanipur residence in south Kolkata, alongside a five-floor apartment in Dakshineswar on the northern fringes of the city and a flat in Joka on Kolkata's southern outskirts, they said.
