The two had floated an investment company and expanded into business of retail stores, edible oil, milk and several branded products.
They allegedly duped gullible investors while promising them high returns with an interest of up to 12.50 per cent, police said.
About Rs 200 crores were collected from across the Vidarbha region and mostly retired government servants and businessmen fell into the trap, they said.
Subsequently, offences under relevant sections of cheating and criminal breach of trust under IPC (406, 420, 34) and provisions of Maharashtra Protection of Investors Deposit Act, 1999, were registered against the couple last night, police said.
No arrest has been made so far, they added.
