Is there any french website which displays news where I could read about this? Sorry but freestylers tend to lie very much like Maccas "I was gone because I was at the hospital" or Andrews and Joshs "Andrew has died" because of some reason I do not remember.
Well, if you look at his latest video:
http://youtube.com/watch?v=-G8Iyahbwdc you can see at 00:15 that he freestyles very close to the road with buses driving by ... So it's not unlikely that this has happened. And if you look at his profile, you can see he hasn't been online for 3 days ...
I hope you get better soon, as good as you were before this accident, and will be able to freestyle again.
Best wishes and good luck,
Tommy
