Malaysian police arrested opposition leader Anwar Ibrahim Wednesday over allegations of sodomy levelled by a male aide, which threaten to derail his plan to seize power. After a long interrogation at police headquarters, he was taken to hospital for a medical examination and would be held overnight at an undisclosed location, his lawyers said. Anwar's wife Wan Azizah Wan Ismail said she feared for his safety, after the events of a decade ago when he was sacked as deputy premier, beaten up by the police chief, and jailed for six years on sodomy and corruption charges. Earlier Wednesday, Anwar dismissed the accusations as a conspiracy to prevent him from seizing power, and said it was a re-run of past events when he was slapped with charges widely seen as politically motivated.
