A former partner of ex-Brazilian Sports Minister Sérgio Cabral has confirmed that Brazil indeed paid money to former iaaf President Lamine Diack to secure votes for the Rio 2016 olympics.
Miranda's disclosure, which was made in the plea bargain, marks the first time that the number of officials allegedly influenced has been named.
Brazil's Federal Public Prosecutors are investigating payments of at least $2 million claimed to have been paid to Diack from a Brazilian businessman Cesar de Menezes Soares Filho in 2009 shortly before the IOC Session in Copenhagen where Rio was awarded the Games.
The Brazilian city beat Madrid by 66 votes to 32 in the third round of a contest which also featured Tokyo and Chicago.
Former Rio 2016 and Brazilian Olympic Committee President Carlos Nuzman was arrested last year in connection with the payments.
He was charged in October by the Federal Public Prosecutor's Office with corruption, tax evasion, money laundering and running a criminal organisation.
Both Nuzman and Cabral have been sentenced to 87 years for various corruption offences and wrongdoings.
"Recently, in prison, Sérgio Cabral told the investigators that Arthur César de Meneses Soares Filho in fact, made payments to African leaders connected to the iaaf.

The Société Générale account was controlled by Senegal's Papa Massata Diack, the son of Lamine Diack, President of the IAAF between 1999 and 2015.
Lamine Diack was a voting member of the IOC at the time Rio de Janeiro was awarded the Olympic and Paralympic Games.
Namibia's former sprinter Frankie Fredericks, also an IOC member at the time of the vote, is currently attempting to clear himself of allegations that he too received financial incentives to vote for Rio 2016.
Documents provided by American tax authorities showed that Papa Diack transferred $300,000 to a Seychelles-based offshore company linked to Fredericks called Yemli Limited in 2009, through a firm linked to him called Pamodzi Consulting.
Although Rio ultimately won by 34 votes, a four-vote swing could have been key in ensuring they remained in the contest in the earlier rounds.
They received 26 votes in round one in comparison with 28 for Madrid, 22 for Tokyo and 18 for Chicago.
Papa Diack is also linked to vote-buying and secret lobbying investigations surrounding the successful Pyeongchang 2018 and Tokyo 2020 Olympic bids.
He has since denied any wrongdoing.
