I have read the same news about this scenario in Hong Kong. And it is the proof that bitcoin and Blockchain technology is traceable transactions. But in fiat it is more common because every personal information is available. And maybe it is also a co-incidents that is not pointed out as the businessman has bitcoin but it is picked accordingly for its wealth and assuming he does have bitcoin on hand. We can also assume that the one offer it is the businessman who will not lost much on bitcoin because he bought it cheaply before.
