LAHORE Pakistan Cricket Board chairman Ijaz Butt has stressed that there is zero tolerance against indiscipline and corruption but he made it clear that the PCB wont be taking any action against any player until proven guilty and has asked the ICC that it was wrong in suspending the players before hand. He said that the three players were not charged in any case and they can return to Pakistan anytime. PCB chief Ijaz Butt extended full support to the tainted trio of Salman Butt, Muhammad Asif and Muhammad Aamir after the three were named in 'spot-fixing. Addressing a press conference here on Thursday, the PCB chief read out date-wise details of what happened in the spot-fixing scenario during his stay in the UK. He further said that fast bowler Wahab Riaz will appear before Scotland Yard next week. He said that the board had officially asked the International Cricket Council not to ban the players and appealed for the final investigation report to come out before any decisive action was taken on the cricketers future. The PCB has asked the ICC not to suspend players. There is no evidence on the trio, the players co-operated with the probe. The PCB cant take any action before the work report is out, Butt said. He also ruled out an independent investigation of their own into the scandal that shook cricket saying that nothing could be done till the British investigation agencies gave their final report and added that the tainted players would be returning to Pakistan soon as there were no charges on them yet. He further said that after all the fuss on spot-fixing, the players would have to get the PCBs recommendations in appointing agents or managers. Any player appointing manager or agent will have to get the PCB approval first and the board will give its final recommendation on the issue, he added. Butt, who was hooted and jeered by angry fans when the veteran administrator landed in the country for the first time since the spot-fixing scandal shocked the world cricket. As soon as Butt came out of the airport terminal, fans raised slogan against him and shouted 'shame shame, expressing their anger over the alleged betting scam which hit the image of the country globally. He further said that fast bowler Wahab Riaz would appear before Scotland Yard police next week in relation to match-fixing allegations. Ijaz said that the left-arm paceman would be interrogated by police on September 14. Riaz will be the fourth Pakistan player to be questioned by police. Test captain Salman Butt, Mohammad Asif and Mohammad Amir had earlier been questioned by Scotland Yard for nine hours before they were provisionally suspended by the ICC last week. He said: Since the players have neither been charged nor there is any restriction on their movement, we have informed the police that they will be travelling back to Pakistan within the next few days. I would like to bring on record the positive and supportive attitude of Pakistan High Commission London especially that of His Excellency The High Commissioner Wajid Shamsul Hasan. The whole High Commission was available at any given moment and input of Additional Attorney General Pakistan KK Agha was also invaluable. Right now, the PCB cant take any action against the players because the ICC anti-corruption unit is carrying out an inquiry into this matter. But if any player is found guilty he will not be spared, he said. Even the police interrogated them for nine hours but let them go without pressing any charges. So, we are also waiting for the ICC and Scotland Yard to come up with their findings into this matter, he added. Butt said that the PCB had filed detailed replies to the charge-sheets issued to the players by the ICC but the world governing body wanted the players to respond themselves. Butt was evasive when asked about reports that the ICC was also investigating the Sydney Test between Pakistan and Australia. I think we shouldnt be talking about such old issues and we need to focus on this current problem and hope it is resolved soon, he added. Butt refused to discuss previous cases of match-fixing against Pakistani players. I dont want to go back in the past, let this inquiry be finished, he said. We are very concerned over the allegations and since we too have zero tolerance against corruption, we also want this to finish soon. We are really worried about the matter and if any player is found responsible then we will take strict action, he added.
