Several people were injured and a man was killed during the celebrations of Napoli’s 33rd league title.
The 26-year old man was taken in a seriously ill condition to a hospital in Naples, where he died later.
ANSA, among other Italian news agencies, reported that friends and relatives of victim vandalized the emergency room to which he was rushed.
Two men aged 20 and 24 and a 26-year old woman also sustained gunshot injuries, but their condition is not considered life-threatening.
Claudio Palomba, Naples Prefect, told RAI that the shooting in Piazza Volturno had nothing to do with the festivities.
La Stampa reported that over 200 people were hospitalized overnight due to injuries sustained during the celebrations. These ranged from burns caused by firecrackers and flares, to asthma attacks brought on by inhaling smoke.
However, Mr Palomba stated that only seven people were injured during the night. Some of them suffered fireworks injuries.
The 1-1 draw that Napoli achieved in their away game against Udinese gave the southern Italian team its first title since 1990 when Argentina’s Diego Maradona won them two titles in 1986-87, and 1989-90.
Fans of visiting Napoli held banners with images of late Maradona in anticipation of the much-coveted Scudetto.
After the final whistle, they rushed on to the pitch. Luciano Spalletti’s team needed just one point to win the league title.
While the players and away end were celebrating in Udine at the Stadio friuli, celebrations erupted all over the city of Naples.
To mark this momentous event, fans flooded the streets with flags, flares, and firecrackers.
“It’ll be chaos and mayhem.” One fan joked, “We won’t sleep and we won’t be working.”
Last week, the US consulate sent out a security warning, stating that “spontaneous festivities could last for several days”. It also warned against “heavy traffic, road closures and significant alcohol consumption in the city.”
“I have been waiting for this Napoli Scudetto ever since I was a child,” said a teenager out with her friends.
She added, “It is a great victory for the city as a whole.

The city centre was festooned with banners, flags and cardboard replicas of Napoli footballers including Nigerian striker Victor Osimhen, and Georgian winger Khvicha Kvaratskhelia.
The Stadio Diego Marando Maradona was equipped with eight giant screens and many Napoli fans watched the match in Naples.
The final whistle sparked fireworks for a crowd of over 50,000 people.
The crowds gathered also at the Maradona Mural in the Quartieri Spagnoli district of the city.
Napoli now has a 16-point advantage over Lazio, who are currently second in the table. There are only five games left to play.
