PKR will launch a Facebook initiative to ask netizens to post any sighting of controversial billionaire Low Taek Jho and four key figures wanted for the ongoing investigations into 1MDB - if the authorities fail to track them down in two weeks.

The reply to Parliament by Deputy Prime Minister Ahmad Zahid Hamidi that police did not trace the five down because nobody asked for police help is indeed shocking, said Wong Chen, PKR’s Kelana Jaya MP.

Wong said Bank Negara Malaysia and the Malaysian Anti-Corruption Commission (MACC) were to blame if they did not ask the police to locate the key persons related to their investigations.

"I now ask central bank governor Zeti Aktar Aziz and MACC chief commissioner Abu Kassim Mohamed to to immediately file reports to request police and Interpol to secure the five to assist in the 1MDB investigations," he told a press coference in the Parliament lobby today.

"Failing to do so within 24 hours will amount to a breach of their fiduciary duties to investigate 1MDB without fear and favour," Wong said.

"If these five individuals are not located within the next two weeks, PKR will launch a Facebook initiative to ask Internet users to help post any sighting of these individuals," he said.

Zahid, who is also home minister, said in a written parliamentary reply to Wong yesterday that police did not track down Jho Low and the four others because the police were not conducting any investigation against them.

He also said nobody had asked the police for help to trace them down.

The other four are the managing director of 1MDB's former subsidiary SRC International Sdn Bhd Nik Faisal Ariff Kamil, Deutsche Bank country manager Yusof Annuar Yaacob, Casey Tang of 1MDB's precursor Terengganu Investment Authority's (TIA) and a former executive director at UBG, Jasmine Loo.

"Since July 22, Jho Low and Nik Faisal have been wanted by MACC for questioning whereas Tang and Loo are sought by BNM. It is public knowledge that the five key witnesses have no longer been in Malaysia since July 2015," said Wong.

He felt that these individuals would not be inherently difficult to locate as they are not "hiding in the caves of Tora Bora but are in fact visibly living the high life".

Wong added: "In the case of Jasmine Loo, she was in fact traced to a high-end US$4.5 million (RM19.6 million) apartment in New York by The New York Times in September this year.

"Earlier this month, her name popped up as a donor to the Black Hall, a society fundraiser event organised by singer Alicia Key."
