Mauro Icardi's agent and wife Wanda Nara reportedly had a rock thrown at her car on Saturday, and Inter boss Luciano Spalletti hopes the culprit is punished.
Argentina international Icardi was replaced as skipper on Wednesday amid ongoing uncertainty over his future at Inter, where he has a contract until June 2021.
The 25-year-old was subsequently omitted from the squad to face Rapid Vienna in the Europa League and the club announced on Friday he missed training due to knee inflammation.
Nara allegedly had a stone hurled at her vehicle while driving and Spalletti wants to see repercussions.
