The ICC has appealed to the public to help identify and find a suspected match-fixer featured in an al-Jazeera documentary on corruption in cricket.

The Qatar-based television station is planning to produce a follow-up to the documentary released this year that made several spot-fixing allegations and has indicated that the alleged fixer, known Aneel Munawar, who remains unidentified, will again play a central role.

“We have identified every other person in the original documentary and have spoken to a number of them in connection with match fixing, including those who are not deemed to be participants under our Anti-Corruption Code,” said Alex Marshall, general manager of the ICC’s anti-corruption unit.

“However the true identity of Aneel Munawar remains a mystery. He plays a significant role in the programme, yet enquiries with law enforcement and immigration sources have not identified or located him.

“As such we are appealing to the public or anyone from within the cricket family to contact us with any information that will lead us to identify and locate him. Police investigations often use such an appeal to locate people of interest and we are exercising the same approach.

“The absence of any cooperation from the broadcaster has slowed the investigation, but to date we have made good progress in identifying people of significant interest including people already of interest to the ACU. We have been able to discount a number of claims made in the programme and continue to pursue other aspects. We will provide a full update at the conclusion of the investigation.”

Meanwhile, Cricket Australia has urged al-Jazeera to cooperate more fully with the ICC investigation.

The new documentary is set to involve claims against current and former Australia internationals relating to historical matches from 2011.

“We are aware of the new investigative documentary by al-Jazeera into alleged corruption in cricket,” the Cricket Australia chief executive, James Sutherland, said.

“Since the broadcast of al-Jazeera’s first documentary the ICC Anti-Corruption Unit has been conducting a thorough investigation into the claims made, however this has been hampered by a lack of cooperation from al-Jazeera.

“Although not having been provided an opportunity to review any raw audio or footage, our long-standing position on these matters is that credible claims should be treated very seriously, and investigated.

“Cricket Australia’s Integrity Unit have conducted a review of the latest claims by al-Jazeera, from a known criminal source, and, from the limited information provided by al-Jazeera, our team have not identified any issues of corruption relating to current or former Australian players.

“We urge al-Jazeera to provide all unedited materials and any other evidence to the ICC Anti-Corruption Unit.”

The Australian Cricketers’ Association chief executive, Alistair Nicholson, said: “The players have zero tolerance for any behaviour that may impact upon the integrity of the game.

“However, enough is enough when it comes to people making unsupported accusations that have the ability to unfairly tarnish players’ reputations. Whoever is making these allegations should provide all the information they purport to have to the ICC to allow them to assess it.”

In the aftermath of the first documentary in May a spokesman for al-Jazeera said: “As our documentary shows, al-Jazeera is fully committed to exposing betting corruption in cricket and we have made it clear that we will cooperate fully with the relevant authorities.

“There are ongoing sensitive legal considerations, including potential criminal investigations into the match-fixing allegations in Sri Lanka and India.

“It is in this context that we are considering the ICC’s request for our unedited material. We will not take any steps that might compromise any civil or criminal proceedings that may follow.”
