The Bank of Tokyo was a Japanese Bank operating in London and a wholly owned subsidiary the Bank of Tokyo Trust Co, a New York corporation. Mr Karoon, an Iranian employee of the Iranian Martime Co had personal accounts with both banks. He left Iran and transferred his money from the New York to the London bank. In February 1980 the London bank was notified that Mr Karoon was sentenced to prison by the Iranian government, and requested his assets be sent to the Iranian government. Mr Karoon asked the bank to transfer his accounts to another bank. The bank, unsure of what to do, applied for an interpleader summons and the money was eventually paid into court.
