Pakistan cricket's tainted trio Salman Butt, Mohammad Asif and Mohammad Aamir will be quizzed by Scotland Yard for the second time on Wednesday in London in the spot-fixing scandal. A Pakistan Cricket Board official said in Karachi that though the trio will be quizzed but they are not in danger of being arrested. He said no player has been charged as yet nor any case registered against them and they are available for the forthcoming Twenty20 and one-day series. The Official said the questioning is part of routine investigation but all the players who are being questioned are available for selection and play in the coming series. A spokesman for the High Commission's office in London also said the tour is on and the PCB has no intention of either sending back any player or calling off the tour. The spokesperson said the PCB and the High Commission are extending all support and cooperation to the investigation. The tainted trio were yesterday barred from team practice at Taunton and asked to proceed to London amidst reports that they would be questioned by Scotland Yard. Though team manager Yawar Saeed said that they would only face a PCB internal inquiry at the High Commission. ICC chief executive Haroon Lorgat on Tuesday said that Scotland Yard and the ICC anti-corruption and security unit were busy gathering forensic evidence and piecing them together.
