Tamil Nadu police officials carried out raids at three places on Sunday after the interrogation of the six bookies held on Saturday.
A senior police official, who is a part of the investigating team that arrested the bookies, said on Saturday that there seemed to be no link with the ongoing spot fixing controversy.
"The Chennai betting operation appears to be an independent one, not linked to the spot fixing in which a top cricketer is allegedly involved," the senior police official said. But the police is examining all angles.
The key bookie Prashant (the bookies' ring leader) to whom the others pay a percentage to be permitted to participate in the booking racket is absconding.
"He has fled to South Africa," the police official said. Prashant's car was found parked at the Chennai airport, police said.
Prashant is linked to a Delhi bookie Sanjay Ahuja, the official said.
Meanwhile, Chennai is preparing for the crucial meeting of BCCI on Sunday, which will decide on the disciplinary action to be taken against erring cricketers.
The board will also decide on steps to prevent the recurrence of similar spot or match fixing incidents in future.
BCCI president N Srinivasan is camping at the hill station of Kodaikanal and is expected to reach Chennai late evening or tonight.
