Prosecutors in Portugal have brought 147 charges, including extortion, against a suspected hacker involved with the Football Leaks website.
Rui Pinto, 30, was held in January in Hungary on a European arrest warrant and later extradited to Portugal.
He is accused of illegally accessing and publishing confidential files belonging to leading football clubs and officials. He denies the charges.
Football Leaks was set up to reveal alleged corruption in football.
What are the charges?
The charges mostly relate to alleged illegal access to data, aggravated extortion, violation of correspondence and computer sabotage.
The prosecutors in Portugal said in a statement that Mr Pinto “used various computer programmes and digital tools to enter, in an unauthorised and anonymous manner, the computer systems or email boxes and remove content from it”.
Mr Pinto, a Portuguese national, has been described as a “computer genius” by local media.
His defence lawyers characterise their client as a “very important European whistleblower”
A trial date is yet to be announced.
What is Football Leaks?
It was launched in 2015 to uncover alleged corruption taking place in football.
Football Leaks provided millions of documents and more than 3.4 terabytes of information to media outlets in the European Investigative Collaborations (EIC) consortium.
The Football Leaks revelations have allowed prosecutors in a number of countries to launch their own investigations.
