Bonucci squared up to Inter General Secretary Cristiano Mozzillo after Alexis Sanchez's late winner
Weston McKennie had given Juve the lead in the 25 th minute but the Milanese side struck back 10 minutes later as Lautaro Martinez netted from the penalty spot.
The game had appeared to be meandering towards a penalty shootout decider as the half-hour of extra time was a low-key affair, prior to Sanchez’s late winner.
That goal sparked wild celebrations in which Sanchez was mobbed by his teammates in the aftermath but on the other side of the pitch, Bonucci was involved in an altercation with an Inter member of staff.
The Italy international is captured on camera to square up with Cristiano Mozzillo, the general secretary of Inter, who had celebrated the goal.
According to a report from Il Tempo, Bonucci said: “You don’t celebrate to my face, what the f*** are you doing? I am going to kill you!”
Mozzillo replied, “What are you doing?” before appearing to attempt to move Bonucci away.
Bonucci is seen to raise his hands to Mozzillo on the video footage while the report claims that several eyewitnesses say that the defender actually struck the Inter official with his fist.
It has been claimed that federal investigators saw the scene unfold in front of them and they have now reported the episode to the relevant authorities.
If that is the case, Bonucci could be punished with a suspension that may last several games.
Sanchez’s winning goal was a huge moment for a player who, despite playing a role in Inter’s first Serie A title in 11 years last campaign, has struggled to rekindle his form in recent years.
Wednesday’s result ensured Inter’s sixth Supercoppa Italiana title – three short of record competition winners Juventus.
Mirror Football has contacted both Inter Milan and Juventus for comment.
Juventus have confirmed that the incident has been reported by an employee of the Federal Prosecutor's Office, but offer no further comment at this time.
