RIO DE JANEIRO, Dec 18 — Rio de Janeiro state prosecutors today raided properties of the former staff of Flavio Bolsonaro, the son of Brazilian President Jair Bolsonaro, and relatives of the president’s ex-wife, according to two sources directly familiar with the matter, rekindling a graft probe involving the president’s son.

The current investigation is an offshoot from an earlier probe looking into suspicious payments to staff from when Senator Flavio Bolsonaro was a Rio state lawmaker. The original investigation was frozen by Brazil’s Supreme Court earlier this year, but later unshelved.

Flavio Bolsonaro has insisted he is innocent of any crimes. However, the investigation has been a stain on him and his father’s young administration, which came to power vowing to kick out years of political graft in Brazil.

Investigators carried out raids at properties linked to Fabrício Queiroz, Flavio Bolsonaro’s former employee at the state legislature who is being investigated on suspicion of helping skim phantom employees’ salaries.

They also carried out search warrants at properties linked to the ex-wife of President Jair Bolsonaro, Ana Cristina Valle, the sources said.

In a statement, Queiroz said he was surprised by the raids, but was unconcerned by them, "since he has always cooperated with the investigations.”

A spokesman for Flavio Bolsonaro had no immediate comment. Reuters was unable to reach Ana Cristina Valle. — Reuters
