A spokeswoman for the prosecutor in Brazil, Paula Amaral, said Luiz Fernando Correa said he spent $ 20 million for the 2007 purchase of safety equipment that further investigation showed was really worth $ 11 million.

"We billed the government more than 80 percent," the spokeswoman said. Amaral said the investigation was conducted because the purchase was made without comparing prices in the market as required by law for all government procurement that is made without a bidding process.

The organizing committee for the 2016 Games said it had no immediate comment on the accusation and said Correa would not make any claim regarding the chrages.

A steering committee stated that Correa continues to lead security for the games. The official was speaking on condition of anonymity because he was not authorized to speak to the media.

Besides being director of security at the Pan American Games, Correa was also responsible for the procurement of services and purchase of equipment necessary to protect the players and managers during the competition, said Amaral.

"In February 2007, he signed a contract for the purchase of intelligence equipment with a consortium of 11 companies that included Motorola Solutions", said the spokeswoman, adding that there was no contract because Correa said it was a matter of national security . Amaral declined to provide details about the equipment purchased.

Karla Otranto, a spokeswoman for Motorola Solutions Inc., said the company had no immediate statements because all the directors were traveling abroad.

Amaral said the evidence of the overbilling was given to a federal judge who will decide whether the case should go to trial.

If the claim is processed and found guilty, the government will have to pay the amount billed in excess.
