Passport verification

Hi, I am RAVI, I applied for passport 20 days ago and book an appointment just after 3 days after submission of the application . I received the police verification at the same day when I went to PSK for document submission. Then very next day police called me to meet him at his police station, It was not an official meet though, more kind of his personal, and he started asking for interrogative like questions. I answered, with a smile, every question he asked. Then he came to ask about bribe like is his right to ask. I said him if u want money, you can go ask the passport authority where I paid 1500. They will surely give you whatever you asking me for. I said him go verify on MEA's passport website, then He started showing some extra over-actions after searching the website he said, "I can't see anything. You should give us money". He was, still not convinced by my answer, again his colleague and he persuading me about bribe. Then I politely told them if you're not getting the sufficient details, I will call them, they will definitely guide you for why to take money from applicants. Thereafter He came to my house for verification and he verified and without self respect he asked my father for money. My father immediately gave him money (500rs). He took the money and went somewhere I don't know where he been. From that day my police verification is still been pending. What should I do for this pls guide me.
