At least one person has died and four others were injured in a stabbing spree at an Italian supermarket.

Reports say the incident happened on Thursday evening at a Carrefour supermarket in a shopping centre south of Milan.

A 30-year-old cashier at the supermarket died after a man started attacking people in Assago.

Among the injured was Pablo Mari, a football player on loan from Arsenal.

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

The attacker has had mental health problems, the reports say.
