Online Fraud in Share Market investment.

I have been lured by a person, who claimed himself to be 'Share Market Expert', to invest an amount of 1.5 lakh INR in Share Bazaar. I shared credential of my Demat account so that he could trade on my behalf. Trading went for a month and he made the money ZERO! He apologised and gave some reasons and asked me to invest further 15k to mitigate the loss and promised to convert this amount to 60k. However within a week, this also turned to Zero! Now he started ignoring me and didn't pick my call. On investigation from my side, I contacted him with another id and proposes for similar investment he actively replied and agreed. Upon asking when was last time he made loss, he said he don't remember. On pressurising from my side, he picked phone and said he can't help anymore and I have to bear all damage. I simply asked him to return back my 15k, which I had borrowed and which he has guaranteed to not make any further losses over it, he denied and block me from everywhere. He runs multiple groups and plunders many ones faith and money. I have his mobile number, email id, chat and call records, his pic, fb id. What could be done?
