Catalan police detained several people after raiding Barcelona’s stadium in a search and seizure operation, adding to the club’s turmoil less than a week before it held its presidential elections.

The operation was related to last year’s “Barçagate,” in which club officials were accused of launching a smear campaign against current and former players who were critical of the club and then-president Joseph Maria Bartomeu.

Bartomeu, his adviser Jaume Masferrer, team CEO Oscar Grau and head of legal services Roman Gomez Ponti were among those arrested, according to reports.

Police said detentions were made but did not say who or how many people were taken into custody.

The club said it offered “full collaboration to the legal and police authorities to help make clear facts which are subject to investigation.” It added the case was related “to the contacting of monitoring services on social networks.”

“The information and documentation requested by the judicial police force relate strictly to the facts relative to this case,” the club said. “FC Barcelona express its utmost respect for the judicial process in place and for the principle of presumed innocence for the people affected within the remit of this investigation.”

The club did not mention Bartomeu, but Spanish media said he and other former club officials were among those detained.

A text message sent to Bartomeu was not immediately answered.

One of the three presidential candidates, Joan Laporta, told Lleida Radio that what happened on Monday “was a consequence of the bad management by the previous administration.” He said the news of Bartomeu’s reported detention was “shocking” and “not good” for the club, but noted that the former president deserved the “presumption of innocence.”

Laporta was Barcelona’s president a decade ago and, like Bartomeu, also faced a no-confidence vote during his time in charge.

Court officials said a judge ordered the search and seize operation but the detentions had been made at the discretion of the police agents involved. Authorities said the operation was being carried out by the police’s financial crimes department.

The company was accused of using fake social media accounts to discredit opposition figures when they expressed views that went against the club. Some of the figures supposedly included players such Lionel Messi and Gerard Piqué, as well as former coach Pep Guardiola.

The club later released an independent audit report showing that there was no wrongdoing.

Bartomeu and his board of directors resigned last year amid fallout from the controversy surrounding Messi. The club has been mired in political turmoil and debt prompted by the coronavirus pandemic.

The club has been managed by a caretaker board since Bartomeu left in October while facing a no-confidence motion supported by thousands of club members furious at the team’s poor performances and the club’s financial situation.

The club’s struggles began to surface after the team’s embarrassing 8-2 loss to Bayern Munich in the quarterfinals of the Champions League last season, which was the first without a title for the Spanish club since 2007-08.

Bartomeu was loudly criticized by Messi, especially after the former president denied the player’s request to leave the club at the end of last season. Messi’s contract ends this season and the Argentine great has yet to say whether he will stay or join another club.
