Register cheating complaint in the concerned police station against the fraudsters.
Persuade police to register FIR otherwise, move your complaint to area Magistrate through a local prudent lawyer.
Now that a complaint was lodged and the real culprit was booked, the accomplice will also be arrested sooner or later. Pool some amount through contribution and contact an advocate for safeguarding your interests and for further follow up. One can not rule out knowledge of owner also, let the police complete their investigation and then study the case.
since the police regd case against the person who has cheated you, police during the investigation will record your statements. You mention the name of the broker also. Police will add the broker as A2.
