(Bloomberg) -- A son of Brazil’s former President Jair Bolsonaro is among the targets of a police operation in Rio de Janeiro as an investigation widens into the alleged misuse of the country’s spying agency.

Carlos Bolsonaro, a councilman in Rio and close confidant of his father, is being investigated for allegedly receiving surveillance information obtained by the agency, known as Abin, on political opponents of the right-wing leader, according to a person with knowledge of the probe. 

Police agents carried out search and seizure orders in his home and cabinet in Rio de Janeiro, the person added, requesting anonymity because details of the operation are not public. The federal police confirmed in a statement it was fulfilling court orders related to the Abin investigation, without naming Carlos or any of its targets.

Carlos Bolsonaro is in Angra dos Reis, on the coast of Rio de Janeiro, with his father and brothers. They had left the family’s house at 5 a.m. to go fishing, before police agents knocked on their door, Fabio Wajngarten, a spokesman for Bolsonaro, said in a post on social media.

Last week, Federal Police raided the home of Abin’s former head as part of an investigation into illegal monitoring of members of the Supreme Court.

Senate President Rodrigo Pacheco said in a statement he is requesting from the top court the names of the legislators who have been illegally monitored by Abin, describing the allegations as “grave.”

Legal problems involving Bolsonaro and his inner circle have been piling up since he left office in 2022. The former president faces investigations over whether he played a role in the Jan. 8, 2023 riots in Brasilia, when his supporters stormed major government buildings in an apparent effort to overturn his defeat to President Luiz Inacio Lula da Silva.

He is also being investigated for allegedly participating in a plot to bug the judge spearheading investigations against him, and for allegedly trying to sell expensive jewelry and other gifts he received as president. Earlier this month, Brazil’s comptroller general found that Bolsonaro was issued falsified Covid-19 vaccine records.

The federal police operation was first reported by local media, including O Globo newspaper.
