Luis Rubiales, the former president of the Spanish football federation (RFEF), was arrested on Wednesday as part of a corruption investigation.

He was released soon after being detained on arrival in Madrid from the Dominican Republic.

He is suspected of receiving illegal commissions when negotiating a lucrative deal to stage the Spanish Super Cup competition in Saudi Arabia.

Prosecutors are seeking a two-and-a-half-year jail term.

Mr Rubiales denies any wrongdoing.
