The Special Affairs Department (Jasa) insisted that ex-BSI banker Yeo Jiawei's conviction in Singapore does not implicate 1MDB president Arul Kanda Kandasamy and Prime Minister Najib Abdul Razak in the 1MDB investigations.

"Many have asked why Yeo was sentenced to 30 years (sic) by the Singaporean court recently.

"The answer (is) Yeo was convicted on witness-tampering charges, in the money-laundering case which was investigated by the Singaporean Commercial Affairs Department (CAD)," Jasa said in a statement today.
