Police will be calling up UMNO Youth deputy head Khairul Azwan Harun over his police report about a conspiracy by certain individuals to topple Prime Minister Datuk Seri Najib Tun Razak and the Malaysian government, said Inspector-General of Police Tan Sri Khalid Abu Bakar.

He said Khairul Azwan would be summoned at anytime to assist the investigation pertaining to his report.

"We call him up at anytime," he told Bernama through the Whatsapp application here today.

Yesterday, Khairul Azwan had lodged a police report at the Dang Wangi police headquarters here alleging that former Bank Negara Malaysia Governor Tan Sri Zeti Akhtar Aziz, former Attorney-General Tan Sri Abdul Gani Patail and outgoing Malaysian Anti-Corruption Commission Chief Tan Sri Abu Kassim Mohamed were believed to be involved in the conspiracy.

Tan Sri Abdul Gani in commenting on the report yesterday had said that the allegation that he was involved in such a conspiracy was just a ruse by certain parties to seek publicity.

Meanwhile, Tan sri Abu Kassim who attended a talk show programme at the Malaysian Institute Of Integrity here today, declined to meet with the media.

He was seen leaving the programme around 10.30am, an hour and a half, after the programme which was also attended by former Prime Minister Tun Abdullah Ahmad Badawi, began.

Meanwhile, in JOHOR BAHARU, the state UMNO youth urged the authorities to immediately investigate the allegation made by Khairul.

"We believe Khairul has strong reasons for lodging the police report.

"As such, we urge the authorities to investigate it immediately to find the truth," said Johor UMNO Youth Head Hahasrin Hashim in a statement.
