One person has died and at least five others have been injured - some seriously - in a stabbing in a supermarket near the Italian city of Milan, police have said.

Local media reported that a 30-year-old supermarket cashier died after a man started attacking people in Assago.

Among the injured was Pablo Marí, a football player on loan from Arsenal. Marí had been shopping with his wife and young son when the attack took place.

Marí, a 29-year-old Spanish defender, suffered a stab wound to the back - but his injuries are not life-threatening. He was conscious and no vital organs had been affected.

Reports say the attacker has had mental health problems and had grabbed the weapon from the supermarket shelves.

The man started stabbing people at random at about 18:30 local time (16:30 GMT) at a Carrefour in a local shopping centre.

"He had his son in a trolley and his wife next to him. He didn't notice anything. He then felt something painful in his back, which was the criminal's knife," Mr Galliani said.

"Unfortunately, he also saw the criminal stab someone in the throat. He saw everything that happened and it was deeply disturbing," Galliani added.

The attacker is reported to have been detained by several customers and handed over to police who arrived at the scene.
