What is 'Barcagate?'
Bartomeu, along with three others - Chief Executive Officer of the club, Oscar Grau, former adviser to the presidency Jaume Masferrer, and head legal counsel Roman Gomez Ponti - were arrested as part of a police investigation into the matter.
The investigation first began following a complaint made by a Barcelona fan group, amid speculation that the Liga side paid I3 ventures for work related to social media monitoring. Some of the work included painting a more positive image of Bartomeu while also seeking to disparage the reputation of several players - including Lionel Messi, Gerard Pique and Xavi.
