A woman in her 70s living in Matsudo City, Chiba Prefecture, received a false call from a man claiming to be a police officer saying that her bank account was being used for money laundering. The woman, who believed her story, opened a new internet banking account at the man's request, had him transfer money from his bank account to that account, and was also forced to purchase crypto assets.
Afterwards, it was discovered that the crypto assets were missing, and the woman was defrauded of more than 200 million yen.
