Arsenal defender Pablo Mari has been injured in an attack in Italy.

One person has died and at least four others injured - some seriously - in a stabbing in a supermarket near Milan, northern Italy, reports in local media say.

They say a 30-year-old cashier of the Carrefour supermarket died after a man started attacking people in Assago.

Among the injured was Mari, who is on loan at Monza from Arsenal.

A 46-year-old suspect has been detained. Police have ruled out any terrorist motive.

Mari, a 29-year-old Spanish defender, suffered a stab wound to the back - but his injuries are not life-threatening. In a short statement, Arsenal said the star was "not seriously hurt" and was recovering in hospital.

Monza CEO Adriano Galliani told Sky Italy that Mari had been shopping with his wife and young son when the attack took place.

"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.

While the executive said the defender had suffered a "fairly deep wound on his back", the knife did not hit any vital organs and he "should recover quickly".

Arsenal manager Mikel Arteta said: "I just found out. I know Edu [Arsenal technical director] has been in touch with his relatives. He's in hospital but he seems to be okay."
