BUENOS AIRES, July 27 (Reuters) - Argentine club Nueva Chicago will have 20 points deducted next season in addition to suffering a 20-match home ban following a riot at a relegation playoff which left one fan dead.The Argentina Football Association (AFA) announced the latest sanction against the club following an executive committee meeting which finished late on Thursday. Trouble erupted during Chicago's match at home to Tigre on June 25 when the visitors, already leading 2-1, were awarded a penalty. Chicago fans invaded the pitch, the match was called off and the trouble continued outside the stadium. The result meant that Chicago were relegated from the first to second division and Tigre were promoted in their place. The home ban was announced by Argentina's interior ministry earlier this month. The points deduction will apply to the second division campaign which kicks off next month. Nueva Chicago's president Antonio Filomeno said the death of a Tigre fan, a 41-year-old man who suffered head injuries, happened outside the stadium in a confrontation with police. 'It has been completely proved that there was not one single Chicago supporter in the place where this person was killed,' he said in a radio interview after Thursday's ruling. 'It happened outside the stadium and involved Tigre supporters and the police.' 'From the first day, they talked about a 20 or 30 point deduction and didn't take into account any of the evidence that we produced,' he said.
