Money fraud

Hi, I am a realtor and 2 weeks ago I have been introduced to a lady client (been told that she is interested to invest in Mumbai) by one of my relatives(earlier he claimed that he knows her well but now he refuses). Few details about her as given by her: she is from London, looking to invest in residential projects (developer project funding). I used to chat with her and also talked over the phone about the requirement, Mumbai residential market, returns, how things work,etc. I have chat records and her pic for reference. Last week on Friday she arrived in Delhi ( she mentioned that she is not getting direct flight to Mumbai) and got stuck at the customs clearance coz she was carrying a DD of higher amount above the restricted limit of getting money in India and asked if I can help her with some amount to pay the penalty as her bank card was not working. She connected me with the customs officer over the phone and then the officer gave me bank details to transfer money so that the client gets free. After some thought I transferred 55k to the said account and asked the officer to release her. After an hours time I got another call telling me that she is stuck in another department and I should send 1.5lacs so that she gets cleared, that officer mentioned something like anti terrorist certificate. Then it clicked to me that I have been cheated. Please suggest me what should I do. How to file a complaint and what will be the consequences. Thank you.
