A former senior member of Malaysia's ruling party said authorities prevented him from boarding a flight on Friday bound for New York, where he planned to lodge a complaint with police against indebted state investor 1Malaysia Development Bhd (1MDB).

Khairuddin Abu Hassan has already lodged complaints in Switzerland and Hong Kong regarding banking activity involving 1MDB, which has been linked to various individuals under investigation in Switzerland for suspected corruption.

Khairuddin said on his Facebook page that immigration officials prevented him from leaving on orders from Malaysian police, who later asked him to report to Kuala Lumpur's police headquarters on Monday.
