Eight other men from North Africa have been reported to criminal prosecutors over the attack on the Jewish Brigade near a fast-food restaurant that also featured kicks and punches.
They were all charged with incitement to commit racial, ethnic and religious discrimination.
The incident was not related to the pro-Palestine demonstration in Milan’s Piazza Duomo.
The marches that took place in Milan and Rome for Liberation Day, when Italy celebrates its liberation from Fascism and the Nazi occupation in World War II, were marred by tension.
In Rome, firecrackers and stones were thrown and pro-Palestinian protesters in Milan managed to break through a police cordon.
