His injuries are not life-threatening, according to authorities.Police said they have arrested the assailant on charges of attempted murder and are investigating his motives.Lee was indicted in February on fraud charges after Haru Invest suspended the withdrawal of approximately 1.4 trillion won (US$1.08 billion) worth of cryptocurrency, which had been deposited by customers from March 2020 to June 2023.During the first trial in March, the courtroom was filled with victims who had lost their investments.
