Luca Corberi and Paolo Ippolito had an incident on track.
After that Corberi retired and throws car parts at Ippolito during the race, neglects Stewards, crosses the track waling back to paddock.
After the race Corberi physically assaults Ippolito and it seems Corberi's family and team members are joining the assault.
