(ANSA) - Rome, September 12 - Italian Soccer Federation prosecutors on Wednesday charged Genoa, club president Enrico Preziosi and 16 players regarding a notorious incident in which the team took off their shirts to appease trouble-making fans last season. The incident took place after hardcore 'ultra' Genoa fans threw smoke bombs and climbed onto pitch-side barriers during a 4-1 home defeat to Siena on April 22, causing the match to be suspended for 45 minutes. The fans demanded the home side remove their shirts, because the players were supposedly unfit to wear them, and all but one obliged - forward Giuseppe Sculli, who was on loan to Genoa from Lazio at the time. The scenes were reminiscent of the rioting by visiting fans that caused an Italy-Serbia Euro 2012 qualifier to be abandoned at the same stadium in October 2010. Genoa had to play two home games behind closed doors because of the trouble.
