KUALA LUMPUR: Malaysian police have arrested a former ruling party official who has traveled the globe to highlight corruption allegations against Prime Minister Najib Razak, his lawyer said Saturday, accusing the government of seeking to silence the whistleblower. Khairuddin Abu Hassan was arrested by police Friday after he was stopped from leaving for the United States where he was to meet with FBI officials, his lawyer Matthias Chang said. He has been charged with plotting to “undermine parliamentary democracy”, a vague charge that critics have said is open to government abuse. “They want to stop him traveling and maybe to intimidate him,” Chang said. Najib’s government has moved to quash further scrutiny of the revelation in July that nearly $700 million was deposited into his personal bank accounts.
