Private equity firm Abraaj Group said on Tuesday it had sold a 21 percent stake in Integrated Diagnostics Holdings (IDH) (IPO-INDI.CA), a healthcare diagnostics service provider, to emerging markets private equity firm Actis.

Abraaj, which has about $7.5 billion of assets under management, declined to reveal the value of the deal or the size of its remaining stake in IDH.
