BRASILIA, May 15 (Xinhua) -- Brazil's Supreme Federal Court on Friday ordered an investigation into the possible diversion of parliamentary funds to cultural projects, including a film about former President Jair Bolsonaro.

The order was issued by justice Flavio Dino after a complaint filed earlier this year by lawmaker Tabata Amaral of the Brazilian Socialist Party.

Amaral alleged that public funds allocated through parliamentary amendments may have been used for electoral marketing and audiovisual content linked to Bolsonaro, who is serving a sentence for an attempted coup.

According to the complaint, several lawmakers from Bolsonaro's Liberal Party allegedly transferred a total of 2.6 million reais (about 514,000 U.S. dollars) from parliamentary amendments.

The case came amid media reports that Senator Flavio Bolsonaro, the former president's son and a presidential hopeful, sought 130 million reais (about 25 million dollars) from a private banker currently jailed on fraud charges.

The funds were reportedly intended for a feature film titled "Dark Horse" about Bolsonaro's life.

Brazilian authorities are seeking to determine whether public budget funds were illegally linked to the financing of the production. The case remains under seal while evidence is being gathered. ■
