It has been revealed that the police officials were monitoring messaging software like Whatsapp and Blackberry Messenger in the scot fixing case that led to the arrests of former Indian pace bowler S Sreesanth along with two of his Rajasthan Royals teammates.

According to a new media report, the Delhi police had around 70 phones under surveillance during their investigations into spot fixing in the IPL. The police said that they found that Sreesanth and the two others were involved in the scandal during their investigations in the spot fixing case. The players were coordinating the fixing arrangements on these arrangements.
