Former Spain Football Federation President Luis Rubiales, infamous for kissing Spanish player Jenni Hermoso without her consent at the Women's World Cup final, was arrested by Spanish police on Wednesday as part of a separate corruption investigation.

He was detained at Madrid's airport upon returning from the Dominican Republic and released a few hours later. An investigative judge is expected to call him in for further questioning in the near future.

Rubiales was returning to Spain amid a judicial probe into business deals while he ran the federation, including his decision to move the Spanish Super Cup to Saudi Arabia.

Rubiales was in the Dominican Republic two weeks ago when police raided a property belonging to him in the southern Spanish city of Granada and the offices of the Spanish Football Federation in Madrid. Seven people were arrested by police before being released, and Rubiales was identified as one of five additional individuals under investigation.

The corruption and money laundering investigation is looking into contracts for the Spanish Super Cup and the federation’s links with Seville’s La Cartuja Stadium, which hosts the Copa del Rey final and some international games, among other deals.

Rubiales stepped down as president of the federation in September after causing an international scandal for kissing Hermoso without her consent at the Women’s World Cup final. He is facing a trial for allegedly sexually assaulting Hermoso. He has denied any wrongdoing in that case.

Rubiales cut short his stay abroad by three days. He had originally told the court that he was coming back on Saturday.

During his time as president of Spanish football, Rubiales overhauled the format of the Spanish Super Cup in 2020, creating a four-team mini-tournament and moving the competition to Saudi Arabia as part of a deal reportedly worth 40 million euros (then $42 million) per tournament for the federation.

Prosecutors opened a probe of that deal in 2022 following leaked audio between Rubiales and then-Barcelona player Gerard Pique regarding millions of dollars in commissions. Pique’s sports entertainment company Kosmos was involved in the deal with the federation and Saudi Arabia. A company official told The Associated Press (AP) that no employee of Kosmos has been detained or placed under investigation and no property of the company has been raided.

In a brief preview of a recorded interview with Spanish television channel La Sexta, Rubiales denied a series of what he called false claims made by Spanish media.

"I don’t know what the judge has said or what Civil Guard has investigated," he said. "The money in my bank account is the result of my work and my savings."

Rubiales, 46, is a former player who ran Spain’s main players union before he was elected to run the federation in 2018 when he replaced Ángel Maria Villar, who was in power for nearly three decades before he was investigated for corruption. Rubiales shored up internal support by boosting revenues for the federation and spreading them around. He worked his way up to UEFA vice president and played a part in securing the joint bid by Spain, Portugal and Morocco to co-host the 2030 men's World Cup.

Spain’s Justice Minister Felix Bolanos, said he was not concerned about possible reputational damage to Spain co-hosting the World Cup.

"The mere existence of this operation shows that Spain’s democratic and judicial institutions work and that helps guarantee the organization and hosting of all international events like a World Cup," Bolanos said.

The federation runs Spain’s men’s and women’s national football teams, the Copa del Rey, and the country's semi-professional and amateur football leagues. It also organizes the referees. The government maintains some oversight of the entity but it cannot name or remove its executives.

Rubiales’ biggest decision was to take the Spanish Super Cup to Saudi Arabia. The clubs and federation liked the income, but the move was criticized by women’s and human rights groups over Saudi Arabia’s treatment of women and minorities.

He had appeared untouchable, however, until he became a national embarrassment for his kiss of Hermoso at the Women's World Cup. The world champion players boycotted the team, and after Rubiales initially claimed to be the victim of "false feminists," he eventually quit under immense pressure.

Since he stepped down, the federation has been run by Pedro Rocha, the man Rubiales maneuvered to leave in charge. Spain's government, reportedly along with FIFA, are pressuring the federation to hold new elections as soon as possible.
