About rates being set by Dawood personally, the chargesheet is expected to state that Pakistan based Salman "Master" was in regular touch with Tinku Mandi, Feroz, Ramesh Vyas and other big bookies in India and passed on the don's word on the odds.
The chargesheet will explain how the Special Cell stumbled upon Dawood's voice in a phone tap. The cops were tracking calls from Pakistan to Dubai and had also put Dawood's number - 923333206**** - under surveillance, although the connection with the wanted terrorist was not then known.
Delhi Police managed to trace a call on the number on March 26, 2013 but remained unaware about who was on the line.
