A court in Portugal on Monday convicted hacker Rui Pinto over his "Football Leaks" revelations that exposed dodgy dealings in international soccer, sentencing him to a suspended four-year prison term.

It was the biggest information leak in sports history and sparked criminal investigations in Belgium, Britain, France, Spain and Switzerland.

Pinto, 34, argued he was a whistleblower acting in the public interest, but prosecutors charged him with 89 hacking offenses and attempted extortion, a crime punishable in Portugal by up to 10 years in prison.
