"Vindoo made several calls to this relative of the Chennai IPL owner. We may call the person in question to ascertain the reasons why these frequent calls were made," an officer involved in the investigation told PTI.
He, however, said it was "too premature" to conclude that the relative of the high-profile owner of the Chennai franchise had links with the betting syndicate.
On whether Vindoo was involved in betting or fixing in earlier seasons of the Indian Premier League, the officer said, "everything is under investigation."
The 49-year-old actor was arrested yesterday for his alleged association with bookies. Vindoo, winner of reality tv show Bigg Boss season 3, was allegedly in touch with some bookies arrested in the scandal. He was on many occasions spotted watching IPL matches and attending post-match parties.
