( CNN ) -- The body of the managing director of one of the richest investment funds in the world was found Tuesday , four days after he disappeared after a plane crash in Morocco , the official Moroccan news agency reported . Sheikh Ahmed bin Zayed Al Nahyan had been missing since his glider plane crashed into a lake in the north African country on Friday . The late sheikh was a brother of the ruler of Abu Dhabi and president of the UAE , Sheikh Khalifa bin Zayed Al Nahyan . Sheikh Ahmed , 41 , was director of the Abu Dhabi Investment Authority . He was also chairman of the board of trustees of the Zayed Foundation for Charity and Humanitarian Works , according to WAM , the official news agency of the United Arab Emirates . The body was found by rescue teams at a dam in Sidi Mohamed Ben Abdellah lake , in Skhirat Temara , a suburb of the Moroccan capital Rabat . Some 225 people -- including over 100 divers from Morocco , the United Arab Emirates , France , Spain and the United States in addition to four emergency physicians -- were called in , the Moroccan Press Agency reported . The body was found by rescue teams in Sidi Mohamed Ben Abdellah lake , in Skhirat Temara , a suburb of the Moroccan capital Rabat . The remains are being transported back to the Emirates from Morocco and are expected to be buried Wednesday , Abu Dhabi TV reported . The ruling family will attend prayers in the Sheikh Zayed Mosque Wednesday afternoon as three days of state mourning begin , the station reported . Forbes ' 2009 rankings of `` The World 's Most Powerful People '' listed the late sheikh at No . 27 . The pilot of the plane was rescued in good condition after the crash , WAM said . The sovereign-wealth fund , which was established in 1976 , is owned by the government of Abu Dhabi . In an interview in January with Germany 's business daily newspaper Handelsblatt , Sheikh Ahmed said he preferred not to use the sovereign-wealth fund label to describe the investment fund . `` We prefer to be seen simply as a globally diversified investment institution , with the difference being that our owner is the government of the Emirate of Abu Dhabi , '' he said . `` ADIA 's sole mission , which has not changed in over 30 years , is to secure and maintain the current and future welfare of the Emirate of Abu Dhabi . '' Asked about news reports that ADIA 's global assets range between $ 300 billion and $ 800 billion , Sheikh Ahmed hewed to the secretive style that has marked the fund . `` As a matter of policy ADIA does not disclose its assets under management , '' he said . But he noted that his brother , the president , who is also ADIA 's chairman , `` has stated publicly that some of the highest estimates seen in the media have been exaggerated . '' But the Sovereign Wealth Fund Institute estimates that ADIA is among the richest investment vehicles of its kind in the world -- if not the richest .
