Gurunath Meiyappan, the son-in-law of the BCCI president N Srinivasan, was on Wednesday ordered by the court to remain in police custody in Mumbai until May 31.
The police, in its remand application, said it wanted Gurunath and Virender "Vindoo" Dara Singh, the actor arrested for alleged contact with bookies, to confront a third suspect - a Chennai hotelier who has also been issued summons by Mumbai police to appear before it on May 31.
"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," additional metropolitan magistrate A M Padwad said.
Gurunath was arrested by Mumbai Police on charges of cheating, forgery and fraud on May 24, after being summoned to Mumbai for questioning over betting and links to bookies. Police investigations suggested that Vindoo and Gurunath were in frequent telephonic contact. Vindoo was also seen in the CSK box at IPL matches.
