Jefferies-linked fund takes legal action against trader Radiant World in London

As well as Radiant World, its founder Pinkesh Nahar, Sapphire Minmetals Corp - another trading firm that used to be part of Radiant World - and Sapphire Minmetals Chairman Rakesh Sethi were named as defendants in the filing. No further information was available.

The CEO of commodity trader Glencore GLEN.L, Gary Nagle, said last month the company considered Radiant World and Sapphire Minmetals to be part of the same group, although Sethi has denied this is the case.

Radiant World, Jefferies and Sethi did not immediately respond to requests for comment on Wednesday. Nahar could not immediately be reached for comment.

Jefferies was told that some of the invoices underpinning its financing to Sapphire Minmetals were not genuine, Bloomberg News reported last month.

The London High Court filing marks the first litigation in Britain in the Radiant World saga.

Mizuho Bank, the banking unit of Mizuho Financial Group 8411.T, has filed a case against the Singapore operating entity of Radiant World, according to the website of Singapore's Supreme Court.

Another creditor, trade-finance firm Incomlend, is suing Radiant World and Nahar in Singapore for $34 million, Bloomberg News reported last month.
