have become significant. Violence by fans has ranged from small fights between fans to tragedies such as the Heysel Stadium disaster and also the Football War. There have been incidents of fans being murdered, such as the killings of Christopher Loftus and Kevin Speight, two Leeds United supporters, in Istanbul in 2000 on the eve of the UEFA Cup Semi-Final first leg. In recent years this aspect of the game seems to have passed its peak in England though it has by no means disappeared completely. Specialist police units and information-sharing between regional and international police forces has made it much harder for the hooligans to organise and participate in disorder. CCTV inside and outside stadiums and also at other anticipated "flash points" such as city centres and railway stations now makes it more likely that people involved in disorder can be identified later even if they are not arrested at the scene. However, there are still disruptions surrounding football matches. One example being the UEFA Champions League matches which were played on 12 and 13 March 2005. Violence by fans has also affected players, including professional athletes, but this is rare. One example includes a message to Christian Vieri, apparently by an Inter Milan fan, which threatened to burn down his restaurant, criticising his attitude towards the team. There is also the notorious incident where the Colombian international player Andrés Escobar was murdered shortly after returning home from the 1994 World Cup. This was reputedly for scoring the own goal which eliminated Colombia from the competition. Before the 1998 FIFA World Cup, 26 Seaburn Casuals (a Sunderland A.F.C. supporters firm) hooligans were arrested in a police raid after a military-issue smoke bomb was let out at a local pub after a fight with bouncers. By the end of the operation, over 60 were facing charges. Some of the Seaburn Casuals hooligans picked up in the raid were also involved with neo-Nazi groups like Combat 18. The operation failed when judge ruled CCTV footage from the pub inadmissible. In March 2002, the Seaburn Casuals fought with hooligans from the Newcastle Gremlins in a pre-arranged clash near the North Shields Ferry terminal, in what was described as "some of the worst football related fighting ever witnessed in the United Kingdom". The leaders of the Gremlins and Casuals were both jailed for four years for conspiracy, with 28 others jailed for various
