(Updates with Mizuho's response)
Mizuho Financial Group (TYO:8411) has filed an originating summons for an injunction against iron ore trader Radiant World in Singapore's Supreme Court.
The case is listed as relating to corporate insolvency, with a hearing scheduled for Friday morning before Justice Kristy Tan, according to the court's hearing list on its website.
Mizuho is represented by Shook Lin & Bok.
The action marks the first public legal move by a lender since Bloomberg reported in July that the trader allegedly provided falsified documents to secure financing.
Mizuho declined to comment to, while Radiant World did not immediately respond.
