3 months ago, one of the biggest Turkish exchange owner had kidnapped and forced to give private key of the cold wallet. Kidnappers stole 150 BTC. So this news is not the first physically stolen Bitcoins via force. I am sure there were some other robberies too.
i hadn't heard about that one. but 2 months ago, a director at EXMO (exchange set up in the UK that caters to people in russia/former CIS countries) was kidnapped and held for a $1 million ransom. the ransom was paid in bitcoins and he was released.
I thought this was the first incident regarding physically taking the bitcoin with force,the cases of these sort of intrusions are increasing on a daily basis and around the globe you have to be careful to whom you are revealing about your assets,because the possibility to steal your money and go invisible is a possibility as most of the countries have not legalized bitcoin or any currency and the investigation is not that easy for a virtual object,unless the robber makes a mistake.
