Mumbai, May 22 (PTI) : A relative of the owner of IPL franchise Chennai Super Kings with whom actor Vindoo Randhawa, arrested in connection with the spot-fixing scandal, was in frequent touch, is under the scanner of Mumbai Police, Crime Branch sources said today.

"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.

Asked if Vindoo had named any Bollywood celebrity who was involved in the betting racket, the officer said, "Vindoo is himself from the film industry and it is natural that his phone contains numbers of several people from the industry. We have not yet got evidence of involvement of anyone of them in betting or spot-fixing."

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.
