Prosecutors said Wednesday that they have received the right-hand man to the mastermind behind South Korea's largest pyramid scheme from Chinese authorities.
  

Prosecutors said they plan to take Kang Tae-yong to their office in the southeastern city of Daegu for questioning after he arrives from the eastern Chinese city of Nanjing.
  

The extradition came two months after South Korea asked China to arrest Kang who faces nearly 30 charges, including embezzlement and fraud.
  

Kang is accused of swindling about 4 trillion won ($3.5 billion) from an estimated 40,000 people between 2004 and 2008, along with his boss, Cho Hee-pal.
  

The two suspects fled to China in 2008. Cho is rumored to have died from cardiac arrest there four years ago, though his death has not been verified.
  

Last year, prosecutors re-opened their probe into the scheme. (Yonhap)
