Felix Baumgartner has gone from hero to villain after being convicted of punching a lorry driver in the face.
The 43-year-old, who became globally famous after skydiving to earth from the edge of space in an extraordinary daredevil stunt last month, has been fined £1,200 by an Austrian court after losing his appeal.
In September 2010, Baumgartner was driving in Salzburg when he overtook a queue of four cars waiting at a roundabout, only for his car to become wedged in front of the other drivers.
A row broke out which saw several people - including the victim, a Greek trucker identified as Dimitrios P - get out of their cars.
And as the altercation continued, Baumgartner - a former professional boxer - punched the 38-year-old lorry driver in the face.
"The punch came out of the blue," Dimitrios told Austrian media. "There was blood everywhere. He was just acting the tough guy and showing off and making himself the hero, but he isn't a hero at all."
Baumgartner had appealed, claiming that he only punched Dimitrios when the lorry driver aimed a kick at him, but the victim disputed that claim.
"I never tried to conceal anything at the court - I admitted that I had tried to kick him but it was only in retaliation," he added.
Baumgartner did not appear in court personally as he is still off on a world tour following his record-breaking jump.
