Argentine football hooligans are believed to have arrived in France to intimidate other fans at the tournament after having been given free tickets by clubs. Members of gangs known as barrasbravas have apparently managed to get free tickets and travel after threatening players and club managers in Argentina. The barrasbravas are organised groups of thugs who provoke violence at matches and extort money from the managers of many clubs. They have been used to intimidate Argentine championship organisers, leading to the deaths of about 80 people over the past five years. Former Argentine international Osvaldo Ardiles said several clubs had ignored government warnings and given out free tickets to barrasbravas who had connections with managers. The president of one second division side has been reported as saying his club had sent a translator along with the 30 hooligans who had been given tickets, in an attempt to stop them misbehaving.
