The Central Bureau of Investigation (CBI), a government agency probing the Satyam accounting fraud, has found that a number of transactions were done through 'hawala,' in the Satyam fraud case. The tainted firm is charged for making salary payouts to over 10,000 false employees working abroad.

The company came into the limelight following the disclosure of the largest ever corporate accounting fraud done by its founder chief B Ramalinga Raju and other top executives of the company.

CBI, with the help of other agencies such as Enforcement Directorate, has arrested three auditors of Price Waterhouse, involved in forging documents and tampering with the records.

A CBI official said: "They were showing on their books the transfer of Rs12 crore every month as salaries. The transfer for one year was Rs144 crore. This went on for seven years since 2002."

It has been established, through preliminary probe, that about Rs1,008 crore might have been transferred to US, UK, Mauritius and South east Asian countries during last seven years. More such revelations are expected, following inputs from US in the first week of August.

The agency said: "The Americans are carrying out their own investigation. In the first week of August, a team is coming to see details of the investigations and how the fraud was carried out."
