Former Barcelona president Sandro Rosell and his wife have been detained in an investigation into his businesses in Brazil, authorities in Spain said.
The detentions are part of a money-laundering investigation related to television rights for past matches of Brazil's national team.
Three other people have been detained, but their identities were not immediately released by authorities.
Police raided offices, homes and businesses in Barcelona and other locations in Spain as part of Operation Rimet, in reference to former Fifa president Jules Rimet.
Authorities said the operation used information from the FBI following the US case against high-level Fifa officials in 2015.
Rosell is already standing trial for fraud and corruption charges involving the 2013 transfer of Brazilian striker Neymar.
