The Pakistan Cricket Board has asked former South Africa coach Mickey Arthur to back up reported comments that he suspected a one-day international against Pakistan in 2007 was fixed.
Arthur, in an interview with a South African website last week, said there were "strong suspicions" of match-fixing when Pakistan collapsed dramatically to lose the fifth and decisive ODI against South Africa in Lahore three years ago.
The PCB has said in a statement that it had served a legal notice on Mickey Arthur asking him to share with PCB any evidence in this regard.
Former captain Shoaib Malik, who led Pakistan in the 2007 series, said Arthur's claims were ridiculous.
