The World Cup winner and his brother Roberto de Assis were first jailed in March when they entered Paraguay with forged passport.
The duo who entered the country for a promotional tour, got their passports from a local sponsor upon landing.
They spent 32 days in a maximum security jail before being transferred to a hotel where they were held under house arrest.
The ex-Barcelona star and his brother both pled guilty to entering the country with fake passports and paid a twenty thousand dollar fine. Ronaldinho’s brother was also released on Monday.
