José Yunes, a former associate and friend of Brazil’s President Michel Temer, was arrested on Thursday as part of an investigation into alleged corruption involving a decree regulating the country’s ports, his lawyer told Reuters.
Yunes served as part of Temer’s administration until 2016 and has been a friend of Temer’s for over 40 years.
A federal police representative declined to comment.
Police are investigating whether Temer took bribes in exchange for shaping the decree in a way that would benefit logistics firm Rodrimar SA, which operates some services in the Port of Santos, Latin America’s busiest container port.
Temer has denied any wrongdoing.
In February, the head of federal police told Reuters that the investigation had found no evidence of corruption.
