Speak Asia, which was registered in Singapore, was introduced in India in early 2010. The company had promised lucrative returns through a multi marketing pyramid model.
The company duped over 24 lakh investors. The amount of scam went up to Rs 2,276 crore. A number of cases had been registered in different states.
According to police, Speak Asia had remitted over Rs 900 crore to Singapore. The money was sent from India to the banks in Singapore and from there to Dubai, Italy and UK. However, the money came back from UK again to UAE (Dubai) and to India.
