The president of the Spanish Football Federation and his son has been held as part of a corruption investigation, police in Spain say.
Angel María Villar Llona was arrested on suspicion of embezzling funds, El Pais and Efe news agency reported.
Mr. Villar, a former Spain international footballer, has been president of the association since 1988.
His son Gorka was among a number of other people also arrested during a number of raids early today.
Spain’s High Court told Reuters that one of its investigating magistrates and anti-corruption prosecutors were leading the probe.
Spanish media report that the allegations centre on the falsification of documents and skimming profits from international football matches.
There has been no comment yet from Mr. Villar, age 67, or his lawyers.
In Villar’s time as president of the federation, Spain’s men’s football team has won two European championships as well as the 2010 World Cup, becoming one of football’s dominant forces.
