Three people were arrested and a fourth is sought after the stabbing attack on Mounir Nasraoui, the father of young Spanish football star Lamine Yamal, in Mataró, Catalonia.
The incident occurred on Wednesday evening, with Nasraoui in serious but stable condition following multiple stab wounds.
The investigation is underway, focusing on the circumstances of the attack, which is believed to have stemmed from an earlier argument.
Lamine Yamal, who plays for FC Barcelona, has gained recognition as one of the brightest talents in world football.
