According to a report in The Athletic, US prosecutors have convicted Ohtani’s former interpreter Ippei Mizuhara of impersonating the baseball star and doing bank frauds

Mizuhara allegedly had already obtained access to Ohtani's bank accounts and changed security credentials to give himself entry. The person on the tape tells the bank employee that he is Shohei Ohtani, then provides a phone number to the bank for authorization -- a number that prosecutors say belonged to Mizuhara.
