According to recent news from the Japanese media, relevant sources said that the Japanese Police Agency was searching the houses of several men. The men traded NEM into other cryptocurrencies in a cointheft of about 58 billion yen (about 3.7 billion yuan) in Coincheck last January. The Police Agency plans to analyze the detained data, conduct further investigations, and conduct a case investigation on these people, with the aim of further ascertaining the situation of the money laundering incident and targeting hackers. It is reported that the incident occurred in the early morning of January 26 last year, when the "private key" information of Coincheck's account holding customers' encrypted assets was stolen. Hackers immediately deposited the leaked NEM points into more than 150 online accounts.
