B Teja Raju, the elder son of Saytam Computer chief B Ramalinga Raju, on Saturday took over additional charge of chief executive officer of Maytas Infra in place of P K Madhav, who was arrested on December 16, 2008 in connection with the Nagarjuna Finance depositors' case.

"It is just an interim arrangement. Teja Raju will oversee those departments, which had earlier been handled by P K Madhav," a spokesperson of Maytas Infra told PTI.

Teja Raju will continue as vice-chairman of Maytas Infra.

Maytas Infra is one of the two companies, which were proposed to be taken over by Satyam Computer.

P K Madhav, who was associated with Nagarjuna group before joining Maytas, was arrested along with Nagarjuna Group's chairman K S Raju alleging that Nagarjuna Finance (group company) had failed to return about Rs 100 crore (Rs 1 billion) to small depositors after maturity.
