Santiago Pedraz, the investigating magistrate in Spain, ruled that he considered Villar, who is also a senior vice-president at FIFA, to be a “flight risk” and should therefore be kept in custody while the probe takes place.

Pedraz also ruled that Villar’s son Gorka and Juan Padron, a RFEF vice-president, should not be freed during the investigation.

Ramon Angel Hernandez, a member of Tenerife’s football federation, had bail set at €100,000 (£89,500/$116,500).

On Tuesday (July 18), Villar was among a group arrested by police in Spain following a series of raids at properties in Madrid, including RFEF’s headquarters, and Tenerife.

The arrests came following allegations of collusion, embezzlement and falsifying documents.

It has also been claimed that Villar sought favours in order to be re-elected earlier this year to the RFEF Presidency, a post he has held since 1988.

Villar, 67, earned 22 caps for Spain during his playing career, which he spent mainly as a midfielder with Athletic Bilbao.

He served as interim UEFA President between October 2015 and September 2016 following the ban of Michel Platini.

It is not the first time Villar has courted controversy after he was fined CHF25,000 (£20,000/$25,600/€23,000) by FIFA’s Ethics Committee in 2015 after failing to cooperate with an investigation looking at the awarding of the 2018 and 2022 World Cups to Russia and Qatar respectively.

He was re-elected as RFEF President in May after a campaign which saw main rival Jorge Perez, the organisation's former secretary general, withdrew from the race after claiming there had been irregularities in the process.

Perez called on the Spanish Sports Tribunal and Sports Council to cancel the election, but this did not happen.
