KUALA LUMPUR (Sept 6): The Malaysian prosecution's key witness in the RM42 million SRC International Sdn Bhd case against former prime minister Datuk Seri Najib Tun Razak was brought back to the country last week, after three months on the run in Thailand, the Sun reported today.

the Sun reported the man, who operates a currency exchange business, was tracked down in Bangkok by a Malaysian Anti-Corruption Commission (MACC) task force which had been looking for him since May. 

"With assistance from [the] Thai police, the MACC team persuaded him to return to Malaysia.

Upon his arrival here last week, he was detained by MACC and placed under a week-long remand. It is learnt that the businessman has since pledged to cooperate with investigators and has agreed to be the prosecution's key witness.

"The businessman is suspected of having aided in many transfers of the multi-billion ringgit in funds linked to 1Malaysia Development Bhd (1MDB) and its former subsidiary SRC International," the Sun reported.

the Sun, quoting sources, reported that the businessman, who is in his 50s, fled Malaysia and went into hiding in Thailand, soon after an investigation on the financial scandals commenced on the orders of the new Malaysian government in mid-May.

"It is believed that the man has vast information on the illegal movement of the funds, both into and out of the country, as his services were engaged by the perpetrators, including the No. 1 person-of-interest, financier Low Taek Jho, also known as Jho Low," the Sun reported.
