Did Raju surrender or was he 'picked up' from home?

Hyderabad: Andhra Pradesh government on Monday gave a version on Ramalinga Raju and Rama Raju's arrests, which contradicts what Chief Minister Y S Rajasekhara Reddy said on Sunday.
Rajasekhara Reddy had said that the Satyam founder and his brother were "picked up" from their house, but Home Minister Jana Reddy told reporters today that they were arrested at the state police headquarters, although popular perception is that the Rajus surrendered."We launched a manhunt for the Raju brothers on Friday. Having come to know that the police were searching for them, the brothers drove to the state police headquarters to surrender.
But the police arrested them immediately," Jana Reddy told reporters here today.Chief Minister Reddy said on Sunday that the police "picked up" the Rajus from their house late on Friday night.
The police action was based on the letter written by Ramalinga Raju to the Satyam board of directors, the chief minister had said."I am giving you the information I have," Jana Reddy said today, while quickly adding that he would give a clear statement on the entire issue in the next three-four days.
