Malaysia's securities regulator on Tuesday said it was unable to "conclusively establish" whether the country's top anti-graft official violated a law on securities trading after conducting a probe.
Azam Baki, chief commissioner of the Malaysian Anti-Corruption Commission (MACC), faced calls this month to explain allegations that he owned millions of shares in two public listed companies in 2015 and 2016.
He has said that his share trading account had been used by his brother and that he had "no interest or benefit in the shares purchased".
