One person was killed and four others were injured, including Spanish footballer Pablo Mari, in a knife attack Thursday in a shopping center near Milan, according to what the media reported, pointing to an isolated act committed by an unbalanced person.

The Italian news agency (ANSA) reported that the 46-year-old Italian, suffering from psychological problems, was arrested moments after the attack that took place in the afternoon in Asago, on the outskirts of Milan.

The agency added that the dead man was an employee of the Carrefour store located inside the mall, where the attack took place, noting that 4 people were seriously injured.

The first elements of the investigation showed that the attacker, who was undergoing psychiatric treatment, seized a knife before attacking several people in his vicinity.

Among the injured is the Spanish football player Pablo Mari, the center of the defense in the Italian football club Monza.

A source close to the club said he was taken to hospital and was still conscious and able to speak.

Club director Adriano Galliani wrote in a tweet: "Dear Pablo, we are all by your side and with your family, we love you, keep fighting as you have always done, you are a fighter and you will recover quickly."
