Former Braskem president José Carlos Grubisich, who was arrested in the United States on suspicion of having a slush fund, had already been reported to the Brazilian Public Prosecutor. His activities were not prosecuted in Brazil, however.
The accusation is in the company's 2016leniency agreement. Controlled by the Odebrecht group, Braskem is one of the largest petrochemical companies in the Americas.
In Brazil the complaint against the executive would call into question the case that sentenced Marcelo Odebrecht to 19 years in prison. Marcelo Odebrecht is the former president of the group and the board of Braskem.
Accused of negotiating Braskem bribes with Petrobras, Marcelo has always denied responsibility, claiming that this occurred before he took over the company's board.
When asked, the Car Wash task force said the agreements produced a large amount of information and each country has developed its lines of investigation, "which are at different stages," according to attorney Deltan Dallagnol.
Grubisich's defense said he was surprised by the arrest, as US suspicions were never raised in Brazil.
