Taher was found guilty of falsifying his age; according to IAAF, it had "emerged that the athlete falsified a birth certificate in order to obtain a Kenyan passport listing his birthday as 1 December 1989, when his real date of birth was 1 December 1986." In addition, his former name was found to be "Dennis Kipkurui Sang". Meanwhile Belal Mansoor Ali was cleared of the same allegations, while the case of Aadam Ismaeel Khamis has not yet concluded. Reportedly, Taher "remained unfazed by the stories of being stripped of his gold medal".
