My Uncle got Scammed

Hello guys, My Uncle got scammed. He is as ex NRI who got back and settled 20 years back. Was communicating with some nun in US (obviously fake profile) who he sent some money as donation. They fedexed bible and some gifts to the address in kerala to gain the trust. And the same story that happens in scam story of donation money coming from outside got stuck in Delhi, need money to release from customs. Long story short they convinced him to send money and assured the cost he sends will be covered once it gets released. He transferred all his savings in multiple transfers over the year in different indian accounts and even sold wife’s Gold going through a mental stage thinking it will all come back. I dont think he did it to make more money. I guess the first transactions was with good will and the rest was him trying to solve it doing damage control thinking he will only get it back one it get released. Obviously they tricked him saying the cost that will incur for him will be covered. And they did get his trust by sending bible and other gifts.

Obviously didn’t share this with anyone until the last week when he asked us for money and had to explain the whole story. Now the damage is done. He in his late 70s doesn’t have any savings or kids to look after him. Is there anyway to get the money back?. I am guessing above 60 lakhs have been transferred over 30 transactions he isnt telling me the exact amount and is still going through the denial stage. I know its been foolish of him but at the same time I feel bad for him, he is devastated and doesnt have money for daily needs anymore. Is filing a case in police station going to help in anyway? He is worried about publicity too. any ideas??
