Jenson Button called for driver Luca Corberi and his father to be barred from motorsport for life after a brawl broke out at Italy's FIA Karting World Championship race.
In an off-screen incident, Paolo Ippolito knocked 23-year-old Corberi out of race, but instead of embracing his fate, Corberi took matters into his own hands.
Ignoring officials' appeals to get behind barriers, Corberi picked up his bumper, walked to the edge of the circuit and hurled it in his rival's direction as the field passed.
Corberi then continued to walk around the facility, crossing the track several times, to return to the paddock where he was involved with Ippolito after the race.
To make matters worse, Corberi 's dad, Lonato circuit owner running the case, physically slammed Ippolito into the paddock fencing.
GPFans understands that the FIA will take action against those involved with FIA karting president Felipe Massa, who attended Lonato, possibly to take the lead.
"After his shameful actions at the FIA World Championships, Luca Corberi just ruined every chance at a racing future," wrote the 2009 F1 World Champion Button on social media.
"His father owns the circuit and is seen pushing the guy into a wall. Please ban both of these idiots."
Massa expected serious action on karting
FIA karting president and ex-Formula 1 driver Felipe Massa is expected to lead serious action after Luca Corberi 's unprecedented assault on a World Championship competitor last weekend.
Lonato, owned by Corberi 's family, hosted the KZ, KZ2 and Academy finals on Sunday.
Corberi is a 23-year-old karting returnee who, a few years ago, stopped full-time competition.
In 2012, Corberi beat F1 drivers George Russell and Lance Stroll and F2 racers Callum Ilott and Dan Ticktum to win the KF3 CIK-FIA World Cup.
Video appeared on Corberi's Sunday, who entered the race for fun, walking to the side of the track with his kart's front bumper in hand after Paolo Ippolito took it.
As Ippolito died, Corberi launched his bodywork. A second video showed Ippolito waiting in the post-race park with his kart, then Corberi sprinting into the field in full-race gear and tackling his opponent.
He physically assaulted Ippolito, who was also confronted by two adult team members, one of whom is understood to be Corberi 's father.
It's also believed the older Corberi confronted Ippolito 's father.
Corberi was disqualified from the race, as was Ippolito for the on-track incident that was the cause, although it is likely to be followed up by the courts.
Former Ferrari driver Massa is president of CIK-FIA and attended Lonato, and The Race understands he won't let such a violent problem pass without further intervention.
Italy's national governing body moved to "fully denounce" the incident and reserved "every possible initiative" against those responsible, while the FIA launched an immediate investigation into the events on Monday afternoon.
A revocation or cancelation of Corberi 's license has been widely mooted, with Massa 's former F1 competitor Jenson Button among outspoken advocates for a "life ban." Button said Corberi had "destroyed every hope" of racing.
As president of CIK-FIA, Massa needs to act quickly and firmly on this shameful, shocking event.
Corberi was thrown out of the conference, but it can't and almost definitely won't be the end.
Calls for life bans for any motorsport athlete hold a harsh tone, and Corberi may have a sensible case for further rehabilitation.
But doing this for a 23-year-old is not the same as a driver in their teens.
Those front bumpers aren't light. Who knows what might have happened if Ippolito's head hit – or another competitor's? And getting too tight with drivers at speed is reckless.
The incident alone warrants a lengthy ban. Subsequently engaging in physical abuse underlines that there is no cause for sympathy with Corberi — or his associates who also sued Ippolito.
It's a great shame for the reputation of international karting as video of the bumper throw and post-race brawl was quickly posted on social media and has received much more popularity than the results of the world championship itself.
Massa and FIA will be forced to act on this cocktail of recklessness and aggression that disreputes the world championship.
For record, the race's winner (and subsequent KZ world champion) was Jeremy Iglesias. With his partner, the Frenchman manages the Brignoles circuit in southern France – they saw the late Jules Bianchi launch his career there and are close to Charles Leclerc 's family. Apparently, Iglesias's win — the first in this category for a Frenchman — was widely cheered.
Few outside the karting world would have noted Iglesias' win under normal circumstances. But it remains incredibly sad and inappropriate, overshadowed this way.
