The racket was busted on May 15 by the Anti-Extortion Cell (AEC) of Thane Police's crime branch with the arrest of four people in Mumbai, including Sonu Jalan alias Sonu Malad,who is believed to be one of the top bookies of the country, the official said.
During the investigation, a "connection" between Jalan and Arbaaz has been established, said Senior Inspector Pradeep Sharma, head of the AEC. "The case investigations are going on since the past five-six years and could involve amounts of over Rs 500-600 crore. We want to find out from Arbaaz what was his role in the entire matter," said Police Inspector Rajkumar Kothmire who is probing the matter.
The 50-year-old actor-producer's cropped up during Jalan's interrogation and recovery of some photographs which include other major film personalities who may be subsequently summoned, he indicated.
According to Kothmire, the entire IPL scam involves some of the biggest bookies operating from Mumbai, Ahmedabad, Jaipur and New Delhi.
Jalan was first nabbed around 10 years ago when the IPL betting scam had erupted and later investigations proved he was in touch with several world personalities, including Arbaaz.
