Shipbrokers in Brazil have come under official scrutiny in the Operation Car Wash corruption probe.

Prosecutors have told a federal judge that they suspect Petrobras officials of involvement in a ­corruption scheme alleged to have favoured three Rio de Janeiro ­shipbroking firms in vessel contracting, documents obtained by TradeWinds show.

The allegations emerged as part of information provided to authorities by a former Petrobras trader and charterer, Rodrigo Garcia Berkowitz.
