The publicist for Brazil's ruling Workers Party and campaign chief for President Dilma Rousseff's re-election campaign is set to be jailed for corruption.
Joao Santana gave himself up to police after an order for his arrest was released, Xinhua news agency reported.
Santana landed in Sao Paulo on Tuesday from the Dominican Republic, where he had been working on the re-election campaign for President Danilo Medina.
Santana has been implicated in the police investigation into the state company Petrobras corruption scandal.
Upon arriving in Brazil, Santana and his wife, Monica Moura, were taken in a police plane to the southern city of Curitiba and driven to the judicial centre which has been leading the investigation into Petrobras.
On Monday, a Brazilian court issued an arrest warrant against the couple for their presumed part in laundering money through offshore companies in tax havens linked to the Brazilian construction giant, Odebrecht.
Brazil's federal police stated they had found documents registering details of Rousseff's campaign expenditures in 2008 and 2012 which showed Santana illegally deposited $3 million in a Swiss bank account.
They also alleged that Santana had been bribed in 2014 by Keppel Fels, the Brazil subsidiary of Singapore oil rig builder, Keppel Corp Ltd.
