Former Ferrari driver Felipe Massa will lead the investigation into the astonishing Kart World Championship incident which saw a driver attack a rival on and off the circuit in separate incidents.
On Sunday video emerged of Italian driver Corberi walking to the side of the race track to throw a loose bumper at a rival, Paolo Ippolito, as he drove past at top speed in a CIK-FIA World Cup race at Italian circuit Lonato. The circuit is owned by the Corberi family.
A second video emerged showing Corberi attacking Ippolito as he climbed from his car post-race before an adult male, later revealed to be Corberi's father, running in to join.
