Previously, Spanish police have stated that the behavior of some supporters is being investigated, and Spanish star Lamine Yamal, who is Muslim, has condemned it.
"Using religion as a mockery makes you appear intolerant and racist," the 18-year-old Barcelona player wrote on his Instagram account last week.
Even Spanish Prime Minister Pedro Sánchez has also condemned the behavior.
Spanish football has been hit by similar incidents in recent years. Real Madrid's Brazilian striker Vinicius Junior has been subjected to racist abuse on several occasions.
