Vikram Agarwal, owner of Chennai's hotel Radisson Blu, has been issued summons by Mumbai crime branch to appear before it on May 31.
In its remand application, the crime branch said it had already confronted 35-year-old Meiyappan with Vindoo, through whom the CSK honcho was alleged to have placed bets on IPL matches, including those involving his team.
The remand application said Meiyappan and Vindoo, son of late wrestler-actor Dara Singh, used to speak in "coded language" during telephonic conversations to exchange information, including those related to players, which could be used for placing bets. "These codes need to be deciphered," it said.
It also said one of the phones that Meiyappan used for establishing contact with Vindoo and bookies was in the name of his employee Kamalnath. "This issue has to be probed further," the remand application said.
Additional Metropolitan Magistrate A M Padwad, however, rejected Ponda's arguments and extended Meiyappan's remand saying, "There has been progress in the investigation. Further interrogation is required so that the investigating agency has a fair chance and complete opportunity to collect material and evidence."
Meiyappan was arrested on Friday midnight for his alleged involvment in betting on IPL matches, raising questions over the future of the Chennai franchise and plunging Indian cricket into a crisis as cries grew louder by the day for Srinivasan's exit as BCCI president on moral grounds.
