Broker cheated me badly

Hi, i have a small company in Hyderabad. One person met me saying that he can connect a good IT projects if I can invest small amount of money rest can be payable based in monthly billing once i receive the payments from US clients, by trusting him i have transferred 7+1Lacs(7 lacs to Calcutta based company and 1Lac for this personnel account, after 1 month we came to know that they just used us for money and their is no such project is available from USA. then we have demanded back our money from Calcutta based company because of our rigorous follow ups they have returned 7lacs to our accounts and remaining this broker who has connected us to them is not responding to our calls and messages, we tried to locate his house as per bank records, but he has shifted from that location 3year back itself, finally we have approached police for justice to locate him, he was harsh on them and saying this falls on civil issue and nothing to do with police. now we need advice how to approach this person to attend us on priority since 6 months he is making us fool.
