Hmv purchased on hire purchase was subsequently seized by forest department

Dear sir, I'm vijay resident of kakinada, andhra Pradesh, my father has purchased a hmv(12 tyre lorry for goods transportation) on hire purchase. After 26 months, because of some financial and family issues , we sold the the vehicle to third party but the finacier rejected the transfer of finance and postponed the transfer for 6 months being their policy. After 6 months we came to know that the vehicle was seized by forest department on the course of transportation of unauthorised commodities by the purchaser of vehicle. We tried our best to bring back the vehicle but the vehicle is still in the custody of the department. Meanwhile, the finacier of the vehicle "indiabulls finance ltd" is pretending us to pay the emi. It was seized in the month of june of 2016 and now in nov, 2017 they are forcing us really hard on it. My father is a lorry driver and I'm being a student don't have any source of income.. We don't know how to proceed and how to face this situation. Please help me regarding this. Thank you,
