Bonjasky, who also won in 2003 and 2004, joins Ernest Hoost and Semmy Schilt as the only 3-time K-1 World GP winners.
However, the Dutch kickboxer's championship win was overshadowed by bizarre actions from final opponent Badr Hari, who decided to try his hand at mixed martial arts in a kickboxing fight.
Frustrated and down on points Hari caught a legkick in the second round and threw Bonjasky on the mat. But instead of waiting for his opponent to stand up, Hari followed down with ground and pound -- and stomp -- and had to be pulled away by the referee.
Bonjasky was awarded the win via disqualification when he couldn't continue due to double vision.
