It has emerged that the chief executive of Qatar broadcaster BeIn Sports is facing allegations of "active corruption" over Doha's bid for the International Association of Athletics Federations (IAAF) World Championships.
Yousef Al-Obaidly has been under investigation since March, along with former IAAF President Lamine Diack, Agence France-Presse (AFP) reported.
Investigating magistrates in Paris are considering charging Al-Obaidly with having participated in the negotiation of bribes, it has been claimed.
Diack is expected to act as a key witness in the matter and will be charged with "passive corruption", AFP reported.
Al-Obaidly has denied the claims.
"I voluntarily attended an appointed meeting as part of a preliminary investigation," Al-Obaidly said in a statement sent to insidethegames by his lawyer.
"The allegations raised are not only utterly baseless and unsubstantiated, but they have been - quite remarkably - leaked to the media.
"For the avoidance of any doubt whatsoever, the allegations are completely and categorically denied and will be vehemently challenged using the full force of the law.
"It would not be appropriate to say anything further."
Al-Obaidly is reportedly close to BeIn Sports President Nasser Al-Khelaïfi, one of the most powerful men in sport.
Al-Khelaifi is the President and chief executive of Paris Saint-Germain, the Ligue 1 club owned by Qatar Sports Investments (QSI), the country's sovereign wealth fund.
He has been elected by the European Club Association as delegate at the UEFA Executive Committee.
But in March it has been reported that he was placed under the status of "assisted witness" by the National Financial Prosecutor's Office for alleged "corruption" and "aggravated money laundering" in relation to Doha's bid for the IAAF World Championships.
At the heart of the investigators' suspicions are two bank transfers, French newspaper Le Monde has reported.
These money transfers were allegedly made on October 13 and November 7 in 2011 for a total amount of $3.5 million (£2.8 million/€3.1 million) to company located in Senegal, Pamodzi Sports Consulting, which is owned by Papa Massata Diack, the son of Lamine Diack.
These payments were provided for in a Memorandum of Understanding with Pamodzi Sports Consulting that Oryx Qatar Sports Investments pledged to purchase sponsorship rights and television rights for $32.6 million (£25.7 million/€29.2 million) provided that Doha were awarded the 2017 IAAF World Championships.
It is claimed that Oryx Qatar Sports Investments is not part of QSI and is owned jointly by Al-Khelaïfi and his brother Khalid.
Al-Obaidly, a graduate of Seattle University, is a Board member of Paris Saint-Germain and QSI.
Doha was overlooked for the 2017 IAAF World Championships - which were awarded to London - but in November 2014 was chosen to host this year's event ahead of rival cities Barcelona and Eugene.
In Switzerland, Al-Khelaifi has been under investigation since 2017 for allegedly criminally bribing the former FIFA secretary general Jérôme Valcke to buy television rights to World Cup tournaments in 2026 and 2030.
Al-Khelaifi has denied the allegations.
Earlier this week, AFP reported that Diack and Papa Massata may go on trial in a separate matter, for allegedly obstructing sanctions against Russia for doping in return for payments.
Prosecutors have recommended Diack, President of the IAAF from 1999 to 2015, be tried for corruption and money laundering.
In another case, Tsunekazu Takeda has been forced to announce he will resign as President of the Japanese Olympic Committee and stand down as a member of the International Olympic Committee after he was implicated in a vote-buying scandal linked to Tokyo's successful bid for the 2020 Olympic and Paralympic Games involving a Singapore company called Black Tidings associated with Papa Massata Diack.
This year's IAAF World Championships are due to take place at the Khalifa International Stadium between September 27 and October 6.
