Italian authorities on Monday vowed to root out hooligans after a rampage by travelling Napoli fans marred the first day of the Serie A season.
''We must root out these gangs of thugs who are polluting our sport,'' said Italian Soccer Federation President Luigi Abete after a day of violence that left a train wrecked and thousands of euros of damage to stations in Naples and Rome.
Italian security police are looking at CCTV footage of the riot at Naples station that forced passengers to make way for fans travelling to the Roma-Napoli game.
Interior Minister Undersecretary Alfredo Mantovano called for the ''utmost severity'' in applying new stricter norms.
As well as stadium bans, hooligans now face criminal charges that can lead to jail terms.
Napoli fans could face a travel ban for the rest of the season.
Last season they had two early travel bans, which they partly ignored, but were taken off a blacklist for good behaviour at later games.
The parliamentary opposition on Monday criticised the police for not ''nipping the situation in the bud'' but also called for faster moves to hand over policing to clubs.
''Do we have to wait for another death for proper action to be taken,'' said centre-left Senator Stefano Pedica, recalling that two people, a Sicilian police officer and a Roma fan, were killed last year.
Police unions called for organised fan clubs to be disbanded and clubs to be fined for incidents of hooliganism.
Naples police chief Antonino Puglisi, who has been criticised for allowing the Napoli fans to leave, was asked to draw up a report for Interior Minister Roberto Maroni.
Monday's papers were full of accounts from dozens of passengers forced to get off an Intercity train to accommodate a spillover of fans from a special convoy.
''We felt trapped in a nightmare, at the mercy of those beasts,'' travellers told Rome daily La Repubblica, which spoke to victims including families returning from their summer holidays and a mother who was taking her seriously ill son to hospital.
The riot, in which four railway employees were left bruised, was sparked when some 200 of 1,300 fans couldn't get onto a special convoy.
They threw a fit when they realised they might be late for the game and started damaging property, threatening to wreck the station unless another train was laid on.
This was when it was decided to put them on the Intercity, but station managers waited for the situation to calm down before allowing the train to leave.
The Intercity eventually arrived in Rome when the game had already started, prompting the fans to let off smoke bombs and leave a trail of damage at Termini Station too.
They went on to wreck 20 out of 39 buses laid on to take them to the Olympic Stadium.
The total damage in Rome was estimated at 60,000 euros.
Damage to the special train was estimated at half a million euros.
Five people - two Roma fans, two Napoli fans and a ticket tout - were arrested at the stadium. They were released on bail Monday.
No arrests have been made in connection with the vandalism.
Soccer authorities decided to authorise special trains again this season after they were suspended following years of damage.
In part, the decision was taken because of a spate of violence between rival fans travelling to matches on their own - especially at motorway service stations.
The fan who died last year was killed by a police officer after a scuffle at a service station.
Sunday's incidents came despite a recent deployment of troops to major cities as part of the centre-right government's crime crackdown.
Termini is one of the sites in the capital where a small troop detachment has appeared.
