A former chief executive office of a government agency was arrested today for alleged corruption after returning from performing the umrah the day before.

It is believed that the case is linked to the earlier arrest of a federal ministry secretary-general, who is now under remand with his two sons after millions of ringgit in cash and gold bars were seized.

It is understood the ex-CEO and secretary-general had both served at the same government agency, the latter on the board of director.

The ex-CEO, 62, is expected to be charged tomorrow for seeking a bribe of more than RM30,000, a source close to investigations said.

He was arrested at his home in Bukit Bandaraya, Shah Alam, the source said.

He allegedly sought a bribe to hasten payments due to an agency's contractor in 2015, and received the kickback at a country club in Shah Alam.

Malaysian Anti-Corruption Commission deputy chief Azam Baki confirmed the arrest.

The agency in an email to the media also said a "Datuk", who is former CEO of a government agency, will be charged at the Shah Alam Court tomorrow.

Malaysiakini is withholding the identity of the ex-CEO and the ministry secretary-general until they are charged with the offences in court.

MACC reportedly seized more than RM5 million in cash and gold bars in the secretary-general's case.

The agency also seized a Toyota Estima vehicle and grants for 10 properties within Klang Valley registered to the secretary-general and his family members.
