"Gurunath and Vindoo were today made to sit face-to-face and questioned," a senior crime branch official said.
The confrontation was crucial for the investigation as Vindoo, soon after his arrest, had told the crime branch officials that he had placed bets on Meiyappan's behalf.
Vindoo was arrested on May 21 by the city crime branch, while Meiyappan, son-in-law of BCCI president N Srinivasan, was arrested late Friday night.
