Unique question

Sirji My father in law offered my uncle to invest in his new start up & uncle wished to invest 3.5 lacs but before he could send the total money his wife interfered & stopped the final 1 lac & then used domestic violence on uncle & threatened him of divorce etc if he doesn't ask father in law to return all the money. Since the money had already been invested to purchase required equipments of the start up father in law had none to return them the money...she then pressurised him harassed him day & night & threatened him of legal consequences & also blackmailed to blame him if uncle & she gets divorced & managed to draft an debt repayment agreement with the help of few powerful people favoring her & got father in law to sign the agreement between herself & father in law & charged certain % of interest also..father in law had no options but to sign since he could not take the risk of being blamed for the separation & breakup of uncle's family with a hope tht he will return the money when business starts earning but this didnot happen.business incurred heavy loss & had to be closed. Now because of tht agreement advantage she sued him & the court allowed him 2 months time to arrange the money but as he was waiting for the court to call him at the end of those 2 months instead of call came the police & took him into police custody..how do we fight her? She used domestic violence & harassment & got a willingly invested fund into a debt which father in law had never borrowed..how can police take someone into custody when the case is in the court & before the court has called him to present himself..it would be logical that had he ignored court's order to present himself on a particular date & time he would commit contempt of court & police wud be sent to arrest him... Please guide. For further contact my email is [deleted] Byeee
