Police have raided an office at the Rio 2016 Deodoro venue cluster as part of an ongoing probe into alleged corruption.

Last month it was revealed that Federal investigators in Brazil had expanded a probe into construction projects associated with the Olympics and were now also targeting all venues to be used at the Games.

According to Reuters, computers, documents, pen drives and other storage devices were taken after police visited the office of a consortium made up of construction firms OAS SA and Queiroz Galvao.

The offices of two unnamed companies were also raided, it was reported.

Initially, the investigation focused solely on transport and infrastructural projects associated with the Games.

Prosecutors claim that federal funding for the Olympics was either overcharged or was spent on work which never took place.

The probe grew from the ongoing Operation Car Wash probe into corruption surrounding state run oil giants Petrobras.

Construction companies paid bribes for inflated contracts with Petrobras, it is alleged, with leading figures across Brazilian society and politics having supposedly profited.

“Representatives of the consortium and authorities from the mayor's office are giving us contradictory information about what happened,” federal prosecutor Fernando Aguiar told Reuters.

“We don't know where the money or the dirt went.”

A Rio 2016 spokesman said that the police raid would not affect work at Deodoro with the Olympic Opening Ceremony looming on August 5.

A Commission has been set up by Rio de Janeiro City Council to investigate whether construction projects associated with the Olympic and Paralympic Games have been hit by corruption.

The five-member panel will spend up to six months examining contracts and other documents concerning venues as well as associated transport and infrastructural projects. 

Three companies implicated in that investigation are also involved in the Games alongside OAS SA and Queiroz Galvao - Odebrecht SA, Andrade Gutierrez SA and Carioca Christiani Nielsen Engenharia SA.

Rio Mayor Eduardo Paes has repeatedly insisted that the Olympics is free of any corruption, but others have remained sceptical.
