Two Juventus supporters are said to have been left seriously injured after flares exploded inside the Stadio Olimpico away end this afternoon.
Italian publication Gazzetta dello Sport reports that as many as 10 Juve fans were injured and had to be transported to a nearby hospital to receive treatment.
It is alleged that Torino followers also attacked the Juventus team coach prior to the derby meeting in Turin, smashing a window and causing further damage elsewhere.
A 2-1 victory for Torino was enough to prevent their arch-rivals from securing the Serie A title this weekend.
