One of the bookies arrested, and named as Amit Kumar, is actually Amit Singh, a former Rajasthan Royals player who was released by the franchise last year.
ESPNcricinfo has learned that Singh, a fast bowler who played in several matches in the 2012 season, was picked up for questioning five days ago but was formally arrested on Thursday in connection with the spot-fixing case that also allegedly involves three current Royals players. Singh, 31, has been identified in the first information report (FIR) as "Amit Kumar r/o Ahmedabad, Gujarat".
Singh has now been suspended by the BCCI pending inquiry.
Singh, who resides in the Bopal suburb of Ahmedabad, played 23 IPL games for the Royals between 2009-2012. He was also part of the Gujarat Ranji Trophy team in the 2012-13 season, last playing against Saurashtra. He'd been in the news for having been reported twice for a suspect action during the 2009 IPL.
