A participant for Real Madrid’s reserve group Castilla, and three players for the membership’s third group, Real Madrid C, have given proof to Spanish police over “the sharing of a private video on WhatsApp,” the membership has confirmed.

Earlier on Thursday, Spanish newspaper El Confidencial reported that the players had been arrested over the filming and sharing of a sexual video involving a minor.

“Real Madrid announced that it has been made aware that a Castilla player and three Real Madrid C players gave statements to [Spain’s militarised national police force] the Guardia Civil in relation to the supposed sharing of a private video via WhatsApp,” the club said in a statement.

“When the club has detailed knowledge of the facts, it will take the appropriate measures.”

The sharing of sexual photographs or video with out consent is against the law below Spain’s prison code.

El Confidencial reported that the arrests passed off on Thursday morning, and had been associated to a criticism filed within the Canary Islands on Sept. 6.
