Tunku Abdul Aziz Tunku Ibrahim has lodged a police report against Tun Dr Mahathir Mohamad over his claim that the King and other Malay rulers have been placed under house arrest.

He said, the former prime minister's allegation was "false and mischievous".

The Malaysian Anti-Corruption Commission adviser noted that several news portals had reported on this.

He said, Dr Mahathir alleged the house arrest was to prevent the King from receiving the 1.4 million people's signatures that he (Dr Mahathir) claimed to have collected.

"By effectively accusing the government of placing His Majesty under house arrest, Tun Mahathir has gone too far, far beyond the bounds of propriety," he told reporters at the Dang Wangi police headquarters here today.

He also rapped Dr Mahathir over his attempt to involve constitutional rulers in politics, as well as partisan politics to his advantage.

Tunku Abdul Aziz said Dr Mahathir's action had caused confusion and could undermine public order and security, and urged the authorities to take immediate action against the former prime minister.
