The scandal took a dramatic twist on 28 August 2015 when a member of Najib Razak's own UMNO party filed a civil suit against him alleging a breach of duties as trustee and that he defrauded party members by failing to disclose receipt of the donated funds, and account for their use. This suit was filed in the Kuala Lumpur High Court and also named party executive secretary Abdul Rauf Yusof. Expressing fear that Najib Razak would wield influence to remove any member of UMNO "for the sole purpose of avoiding liability", the court was also being moved for an injunction to restrain UMNO, its Supreme Council, state liaison body, divisions and branches from removing the nominal plaintiff as a party member pending the determination of the suit. The plaintiff is also seeking a repayment amounting to US$650 million, the amount allegedly deposited by Najib Razak to a Singapore bank, an account of all monies that he had received in the form of donations, details of all monies in an AmPrivate Banking Account (No. 2112022009694), allegedly belonging to Najib Razak, along with damages, costs, and other reliefs. One of the UMNO representatives, Anina Saadudin, who filed the lawsuit, was immediately expelled from the party. Another police report was filed by a Johor UMNO member, Abdul Rashed Jamaludin, against Najib Razak, over the funds that went into his bank account and other wrongdoings at 1MDB. Another UMNO member, Khairuddin Abu Hassan, and his lawyer Matthias Chang, has submitted evidence on the 1MDB scandal to the Swiss attorney general for investigation into whether any Swiss banks had done business with 1MDB Khairuddin also lodged a police report in Hong Kong against Najib Razak and Jho Low, pertaining to four companies: Alliance Assets International, Cityfield Enterprises, Bartingale International and Wonder Quest Investment, which had purported dealings with 1MDB. Khairuddin and Matthias were barred from leaving Malaysia after confirmation from immigration officials who were under orders by the police to prevent them from leaving. Khairuddin and Matthias were charged under the Security Offenses Act (SOSMA) under the pretext of sabotaging Malaysia's banking and financial sector. The opposition People's Justice Party (PKR) has filed a lawsuit against Najib Razak, Tengku Adnan Tengku Mansor, 1MDB and the Election Commission accusing them of violating election laws on campaign expenses, using funds from 1MDB.
