Ramalinga Raju was the former chairman of Satyam Computer Services from 1987 to 2009. He confessed in January 2009 that he had committed fraud of over Rs. 7,136 crores by creating fake invoices and bank statements. An investigation found that Raju had used the fabricated revenues to purchase land and try to sell his other companies to Satyam. A special board took over Satyam and sold it to Tech Mahindra in order to protect the interests of 53,000 employees. In 2015, a court sentenced Raju and the auditors involved in the fraud to 7 years in prison and a fine of Rs. 5 crores.
