Haider questioned the selection of Kamran in the national team for the coming series against Australia and the World T20.
Lahore: The Pakistan Cricket Board has asked discarded wicketkeeper-batsman Zulqarnain Haider to present evidence to back up his corruption allegations against Kamran Akmal and other unnamed players by August 31 or face disciplinary action.
PCB's Chief Operating Officer Subhan Ahmed told the media that the Board had taken serious notice of the latest outburst by Haider on his facebook page and in media interviews.
"We have taken serious notice of his latest allegations because when he was pardoned by us he had assured us he would be on his best behaviour," Ahmed said.
"We have sent him a letter asking him to provide our anti-corruption officers the evidence or details he has to back up the allegations he has made against other players," he added.
Haider, in his latest outburst, questioned the selection of Kamran in the national team for the coming series against Australia and the Twenty20 World Cup.
He claimed that Kamran had not been cleared by the International Cricket Council and the PCB had selected him despite suspicions about his behaviour.
Haider threatened to make more startling revelations about other players in the team if Kamran didn't produce the clearance certificate given to him by the ICC.
