PAKISTAN found themselves at the centre of fresh ball tampering allegations at the cricket World Cup on Wednesday. Wasim Akram’s side have been reported for interfering with the ball by match referee John Reid of New Zealand after the second round match against South Africa last Saturday, a Pakistani source told AFP. The source said: “Match referee John Reid had an argument with our manager Zafar Altaf about the ball after the match. Reid felt it may have been tampered with.” Altaf confirmed speaking to Reid, but said the team was not unduly concerned by the allegations. South Africa and Australia have both asked for the ball to be changed late in the innings to prevent Wasim Akram and his fellow seam bowlers from getting the reverse swing they are famous for.
