Spanish police raided the offices of the referees’ committee as part of an investigation into Barcelona’s alleged corrupt payments to an official.

Barcelona face charges of corruption over payments made to Jose Maria Enriquez Negreira, a former vice-president of the committee, in return for favourable refereeing decisions.

Uefa is also investigating the matter.

Barcelona deny any wrongdoing and no arrests were made during the search in Madrid.

The Spanish Civil Guard searched the Spanish Technical Committee of Referees (CTA) headquarters on Thursday.

BBC Sport has been told that the judge presiding over the case demanded documentation from the CTA. This was not sent, which prompted the raid.

The initial criminal investigation was brought by the Barcelona public prosecutor’s office in March, with European football’s governing body Uefa launching its own investigation shortly after.
