Michael Schumacher celebrated winning a record sixth world title yesterday — by trashing a hospitality suite.

He and brother Ralf left a trail of debris with boozy hi-jinks after the Japanese Grand Prix.

The paddock was strewn with Bottles, Michael hijacked a forklift truck and Ralf threw a TV through a window.

Cleaners had to spend hours clearing up a mess of trodden food, shattered glass and spilled booze.

A witness said: “They looked as if they had gone wild. It was like a war zone.”

Racing drivers normally drink little and are well behaved. But the incident, which also involved French star Olivier Panis, showed that not only football has its unwelcome side.

The German aces caused chaos after Ferrari’s Michael, 34, clinched enough points at Suzuka to make him the most successful driver ever.

He broke the record of five championships set by Argentinian legend Juan Manuel Fangio in the 1950s.

Ralf, 28, had been livid with his brother for almost squeezing him off the circuit — and the pair decided to patch it up over a drink.

The witness added: “It started with them throwing drinks and escalated.

“Michael, who was smoking a big cigar, handed Ralf the TV and he threw it out the window. Michael and Olivier picked up a couple of tables and chairs and lobbed them at the broken window.”

It is understood Ralf jumped into an on-loan BMW to drive to their nearby hotel.

But Michael, who also sent a fridge toppling over, hopped on to the forklift for a spin round the paddock.

He then pulled Ralf out of the BMW driver’s seat and jokingly took the wheel — but did not drive off.

The Suzuka race is renowned for drivers letting their hair down at the end of the season, but antics are usually confined to chucking water over each other.
