The Italian police have arrested 12 leading Juventus hardline fans linked to violence and fraudulent selling of match tickets.
The suspects are being accused of criminal association, money laundering and violence.
According to the Italian media, they began by singing racist chants during matches which could lead to the club being hit with fines and possibly having points deducted.
It started after Juventus stopped distributing tickets for resale in 2017.
Police said the groups had set up a “widespread criminal strategy to restore lost favours”.
Those arrested included the heads of the Drughi, Tradizione-Antichi Valori, Viking, Nucleo 1985 and Quelli di via Filadelfia groups, it said in a statement.
