Daniel Och, the founder of alternative investments firm Och-Ziff Capital Management will make more than $2.5bn (€1.74bn) from the flotation of his business and the sale of a stake to a Dubai-based investor.

Daniel Och founded the firm in 1994 with the Ziff family and last night agreed to sell a 9.9% stake, or 31.8 million shares, in Och-Ziff Capital Management to Dubai International Capital, an investment firm backed by the emirate's ruler, at the same time as a similar number of shares are listed in New York. Och will still be left with a 48.5% stake.
