Three German football fans and five Italians were arrested following violence in Naples before and after Napoli’s Champions League win over Eintracht Frankfurt, a local official said on Thursday.

Six police officers were injured in violence on Wednesday evening, according to Alessandro Giuliano, who is responsible for public safety in Naples.

Police were in the process of identifying 470 German fans who arrived in the city, and were scouring images to establish those responsible for the disorder, he told a press conference.

Dozens of supporters of Atalanta also joined forces with supporters of the German side, with whom they are twinned.

The first clashes occurred on Wednesday afternoon in Naples’ historic centre, and continued after the match, an easy 3-0 win for Napoli which took them through to the Champions League quarter-finals for the first time.

Smoke bombs and flares, chairs, bottles and metal poles were thrown at police, who responded with tear gas. Later, Napoli fans were filmed by Italian media throwing objects at buses carrying Eintracht fans.

Naples mayor Gaetano Manfredi condemned the “unacceptable” violence, while opposition politicians have questioned the government’s handling of the situation, notably by Interior Minister Matteo Piantedosi.

Napoli player Juan Jesus said the disorder was “bad for the city, and bad for football”.

“Because people come, then destroy, then leave, it’s not a good thing. It’s not possible to still see this in 2023, we are sorry to see these scenes,” he said.

The German supporters had travelled to southern Italy, with many arriving in Naples by train, even though Eintracht decided against selling tickets for the away section in Naples for the second leg of the last 16 tie.

The Frankfurt club decided not to take up their allocation after the Naples prefecture decided on Sunday to ban residents of the German city from buying tickets.

A earlier Italian ban on Eintracht fans who lived anywhere in Germany was overturned.

Sunday’s decision came after violence in the first leg that was won 2-0 by Napoli in Frankfurt, which led to nine people being taken into custody.

Eintracht fans have been under close surveillance by European governing body UEFA since the pitch invasion which greeted the club reaching the final of the Europa League, which they won by beating Scottish club Rangers.
