According to sources, quite a few names from the film industry are doing the rounds in connection to Singh's arrest but most film personalities reportedly do not interact with Singh directly.
They said the betting rate is fixed through his peon, bodyguards or office staff and that makes it immensely difficult to prove the involvement of any actor.
A senior actor, who had confessed to betting in 2005, said he had left the business, adding that betting is a small offence and one can easily get away on a bond of Rs 950.
Speculation is rife that an actor, brother of a popular actor, is on Singh's list. The latter is also popular with many starlets who indulged in betting activity through him.
Police sources said that a popular TV actor, who recently appeared in a remake of a Pakistani serial , is also known to have involved herself in betting.
Sources also said that while women did not pay any role in Vindoo's dealings, an actor-turned-director plays a big role in supplying escort girls to cricketers. Some Maratha film starlets are also suspected to have worked as honey-traps in the spot-fixing case.
