At least two men, one a fan and the other a police officer, have been shot in the lead up to the Coppa Italia between Fiorentina and Napoli in Rome. Outside of that, we don't know much at this point. The start of the match has been delayed while everything is sorted out.
Reports are varied, but at least two, and perhaps as many as four, people have been shot in Rome, one of whom was an undercover cop. Another report claims the injuries resulted from a nailbomb explosion. From this write-up, Google-translated from the Gazzetta Dello Sport, it seems that two fans were shot, one in the arm and the other in the chest and third victim was an undercover cop.
The police officer (43 years) was wounded in the right hand, the other one (30 years old) was shot in the chest and was admitted to Villa San Pietro dying: the bullet, fired from close range, is stuck in the spine. A fourth person aged 32, wounded by gunfire shot in the arm and wrist, is admitted to the Holy Spirit.
BEIN is reporting that a fan was murdered. Not much is known about how the shooting began, but it was said many Napoli fans had gathered in Tor di Quinto and tried to get around security barriers when things went south. The shooting has been attributed to either a frightened shopkeeper.
We'll update as we learn more.
