The CBI has charged Satyam founder B Ramalinga Raju, his brother B Rama Raju and eight others with creating fictitious customers and siphoning off Rs 430 crores from the IT firm.

According to the supplementary chargesheet filed last month by the CBI, which probed the accounting scam in the company, the accused created fake customers and generated invoices against them in order to inflate revenues of Satyam Computer Services Limited (SCSL) to the tune of Rs 430 crore, incurring expenditure to the tune of Rs 65.88 crore.

"Adequate evidence has come on record to prove that the accused Rama Raju, SCSL employees G Ramakrishna, D Venkatpathy Raju and Srisailam have dishonestly and fraudulently conspired together to create seven fake customers in 2006 and got forged and fabricated invoices raised in the name of those customers to the tune of Rs 430 crore in order to inflate the revenues of SCSL to that extent," the chargesheet said.

In order to inflate the account books, the accused created fake email IDs and sent mails on behalf of the seven customers to various associates of SCSL and urged them to continue the development of the products.

After an analysis of the emails, it was found out that the Internet Protocol addresses used for sending the mails were from within Hyderabad, clearly revealing the mails had not emanated from the seven foreign customers, the chargesheet said.
