Five new cases were registered against Lee Capital Services Private Limited in the district on Saturday for cheating investors using a money-chain model. The police said initial estimates pointed to more than Rs.30 crore of fraud in Kozhikode alone. The investigation into the firm’s dealings was ordered following a complaint from an investor who lost Rs.3,80,000. The company attracted investors by offering up to Rs.3,000 interest for Rs.1 lakh a month.
