Last week, the ED's Mumbai Zone conducted searches at 29 premises across six cities-Mumbai, Nashik, Ahmedabad, Gandhinagar, Surat and Bhavnagar-under the Prevention of Money Laundering Act (PMLA). The case relates to R M Drip and Sprinklers Systems and R&B Denims, the agency said. According to the ED, the two companies issued more than 35 million shares and convertible warrants through preferential allotments between April 2023 and March 2024. A substantial portion of the funds allegedly came from a small network of connected individuals, firms and lenders, it said.
