there was an auction/sale notice in the newspaper and the property was sold to the highest bidder and 25% amount was kept deposited by the bank on the terms that the balance 75% of the said amount would be deposited within 45 days. in the mean time the successful bidder took possession of the property with conivance of the bank. the said bidder created boundary wall and encroached some neighbourhood properties and repaired some part of the property with the help of local musclemen and also with a conivance with the bank. on enquiry we issued a letter to the bank stating the facts and requested them to take necessary action and also to take back the possession. the bank kept silent. after 45 days of the time we found that the amount has not been deposited and that the bank also has not taken any steps. we approached the bank to take appropriate legal action against the bidder and or to cancell the bid and return back the possession. the bank is not replying to our letters and are silent. we have recently come to know that the said bidder has created liabilities of around 5 lacs from local supplies and has run away from the said property. the bank is not taking any action and are silent about the subject. what should i do now? what will happen about the deposit amount? and what will happen about the liabilities created ?
