The failure of the 1Malaysia Development Berhad (1MDB) chief executive officer Arul Kanda Kandasamy and former CEO Datuk Shahrul Ibrahim Halmi has drawn the ire of Datuk Nazir Razak.

Nazir who is the brother of Prime Minister Datuk Seri Najib Razak took to Instagram to vent out his frustration after the two top officials had failed to appear before the Public Accounts Committee (PAC) hearing, scheduled today.

"Your company has triggered a national crisis and you can be too busy to face parliament? Unacceptable," he wrote on his Instagram account.

Shahrul Ibrahim was 1MDB’s first CEO from February 2009 until March 2013, while Arul Kanda was appointed in January this year.

Earlier today, DAP’s Lim Kit Siang had also questioned the duo for failing to attend the PAC hearing.

“Have Arul and Sharom good reasons for playing truant from the scheduled PAC hearing on the 1MDB scandal today, when the duo had been given more than two weeks’ notice of the hearing?,” Lim questioned in a statement today.

He also questioned why wasn’t the PAC informed immediately if the duo could not attend the hearing as they had received the PAC requisition on May 6.

The PAC was only informed via a letter from the Finance Ministry on May 22 that the duo could not attend as they had overseas appointment.

Yesterday, PAC chairman Datuk Nur Jazlan Mohamed said the duo were given one month's extension and promised that the postponement did not mean that the investigation proceedings on 1MDB will be delayed.

Nur Jazlan also said PAC will be taking statements from three firms which had audited 1MDB’s accounts.

He said the firms – Deloitte, KPMG and Earnst & Young – are the main witnesses in the proceedings.

1MDB had been under the spotlight over the last few months after various quarters had alleged mismanagement of funds and poor investments by the government-owned strategic development company.
