Sanjeev Saxena, once considered close to Amar Singh, holds the key to unravel the 2008 'cash-for-vote scam', Delhi Police said on Monday as it prepares itself to launch a search for a driver and a mobile phone used by him at the time of delivery of cash.
Investigators, who consider Saxena as the "key player" in the whole scam as he carried money to the three BJP MPs to be bought over for voting in favour of UPA government during the trust vote on July 22, 2008, is preparing to question more people in the scam and if needed, more arrests.
Saxena was arrested on Monday, two days after the apex court came down heavily on Delhi Police for its "callous approach" in probing the scam and asking why it has not taken action so far against those involved in the case.
Police expressed the hope that his questioning will lead to unravelling of the events which led to the scam and who were behind the whole drama.
"Our immediate priority is to locate the mobile phone used by him at the time of delivery of the money as it was allegedly used in conversations among BJP MPs and Amar Singh," a senior police official said.
Police is also looking for one Sanjay, the then driver of Singh, as he was with Saxena at the time of delivery of the money to the MPs, the official said.
The official said police have crosschecked statements of the MPs and it stood corroborated with the video footage of a sting operation carried out by a TV channel.
The official claimed police had collected enough evidence against Saxena. "He is giving contradictory statements but we will crack him," he said.
The official said the investigators may question Amar Singh, Sudheendra Kulkarni and a few others in the coming days.
