President Aurelio De Laurentiis was involved in an altercation with a Napoli fan after the defeat to Parma.
The patron, who continues his other work as a Hollywood movie mogul, was in the stands of the Stadio Tardini for the 1-0 loss this evening. 
RAI programme La Domenica Sportiva were trying to interview De Laurentiis when he suddenly veered off out of his car to engage in an altercation with a Napoli supporter.
The security staff quickly pulled them apart and De Laurentiis returned to his vehicle before being driven away.
It is also reported by La Domenica Sportiva that Napoli barred their players from speaking to them this evening after realising the incident had been filmed.
