Liquidators from Deloitte, overseeing the break up of Abraaj Group’s private equity unit, are asking the Dubai firm’s investors for additional legal protection and more money, the latest complication in the proposed sale of Abraaj’s assets.

Representatives of the accounting firm have asked Abraaj backers for assurances that it won’t be sued over its role in the sale of some of the private equity firm’s Africa and Middle East funds, people with direct knowledge of the insolvency process said.
