Chinese police from multiple cities have arrested three individuals who allegedly stole bitcoins and other cryptocurrencies worth around $87 million. The police further accused the group of having conducted a series of illegal cyber intrusion into corporations and personal networks to obtain crypto assets, with an initial estimation of 600 million yuan, or about $87 million. It also comes at a time when Chinese police have stepped efforts to crack down cyber-crimes that relate to cryptocurrency. Previously, police in China's Dalian city also arrested 20 suspects from a computer technology firm who allegedly used crypto mining malware to infect over a million computers and reportedly earned more than $2 million over two years.
