At least one fan and one police officer have reportedly been shot ahead of the Italian Cup final between Napoli and Fiorentina in Rome.

The football supporter was believed to have been hit in the chest and was in a serious condition, while the police officer was shot in the hand.

The shootings reportedly happened in an area where fans were gathering for the match at the Olympic Stadium.

There were also reports of serious crowd trouble in the Tor di Quinto area close to the venue.

At least three Napoli supporters were reportedly injured in clashes, as rival supporters threw firecrackers and other objects at each other.

Fans of Roma, one of the capital’s clubs, were also reportedly seen throwing bottles and stones.

Inside the stadium, Napoli captain Marek Hamsik was seen going over to talk with the fans and calm them down before kick-off, which was delayed by 45 minutes.

Napoli overcame the dramatic scenes to claim their second Italian Cup trophy in three years with a 3-1 win over Fiorentina.

There was more chaos at the final whistle when Napoli fans invaded the pitch to celebrate, although they were quickly brought under control.

Italy’s Prime Minister Matteo Renzi and Senate President Piero Grasso were present at the game.

Mr Grasso, who presented the trophy to Napoli at the end of the match, described those responsible as “delinquents, not supporters”.

“A game of football cannot be turned into a war between rival gangs,” he said
