( CNN ) -- Two leading world sports officials were sanctioned by the International Olympic Committee Thursday over cash payments they received from a collapsed sports marketing agency . The IOC executive board meeting in Lausanne handed down a warning to IAAF president Lamine Diack of Senegal , while Cameroon 's Issa Hayatou , who heads the African football conferederation ( CAF ) , was reprimanded . But both will remain as IOC members . The board was acting on recommendations made by the IOC Ethics Commission , who launched an investigation into corruption after a BBC television documentary which accused both men of taking money from International Sports and Leisure ( ISL ) . The agency , which was declared bankrupt with debts of around $ 300,000 in 2001 , had among its clients FIFA and the IAAF , which runs world athletics . The documentary also placed former FIFA President Joao Havelange under the microscope . The 95-year-old Brazilian resigned as an IOC member earlier this week and the case against him was closed . IOC President Jacques Rogge told a media conference Thursday that the fact Diack and Hayatou were not IOC members at the time they had taken money was a `` mitigating circumstance . '' He added : `` The IOC has proved that we have a high respect for ethical behavior . '' He refused to comment on Havelange 's resignation . Havelange resigns from IOC . The details of the findings in the cases against Hayatou and Diack were published on the IOC official website Thursday . Hayatou admitted in his evidence that he had received 100,000 French francs from ISL in 1995 , but claimed that it was used to celebrate the 40th anniversary of CAF , which he has headed since 1987 . He produced minutes of a meeting in 1998 and a note from the CAF Finance Director from March 2011 to back his claims , but the IOC cast doubt on his explanation . `` It ( the Ethics Commission ) noted that the documents produced by the person concerned , drawn up a long time after receipt of the funds , do not guarantee that the payments were indeed made into the CAF accounts , '' read their ruling . `` It considers that personally accepting a sum of money in these conditions constitutes a conflict of interests . '' Diack confirmed that in 1993 he had received three cash payments totaling $ 30,000 and 30,000 French francs from ISL executive Jean-Marie Weber . He said Weber had given him the money because he felt sorry for him after his house was burnt down `` for political reasons '' in March 1993 . He denied any connection between the marketing contract that ISL and the IAAF , of which he was then a vice-president , signed in June that year . The Ethics Commission took into account his personal circumstances at the time , but added : . `` It notes that by accepting a cash donation in these conditions from a marketing partner of the International Federation of which he was vice-president , Mr Lamine Diack placed himself in a conflict of interests situation . '' Hayatou 's reprimand is a more serious sanction , but Rogge confirmed both men will be able to continue all their duties as IOC members .
