The confrontation happened in October 2014 while Pique was waiting in the passenger seat of his brother’s illegally parked car.
The judge heard that the 28-year-old husband of Colombian singing star Shakira tried to persuade the police he had only stopped for five minutes, but his excuses were ignored.
When given the parking ticket the footballer screwed it up and threw it at them while insulting them in a an offensive manner.
A fine of 900 euros was recommended but the judge told the court that due to Pique’s high salary at Barcelona the fine was being raised to 10,500 euros (11,600 dollars, 7,600 pounds).
Pique was not in court Wednesday but made a public apology via his Twitter account at the time, claiming the incident had been blown out of proportion, but saying he was very sorry and wouldn’t do it again.
Pique has won the Champions League with Manchester United and Barcelona, while with Spain he won both the World Cup in 2010 and Euro 2012.
