In the middle of a hold-up at a convenience store in Vancouver, Canada, a young man in a wheelchair appears on the scene, balancing on two wheels and showing he knows his Jiu-Jitsu by attacking the nervous robber with a rear-naked choke. The thug did manage to escape, only to end up in an arm-triangle, where he remained until others arrived to help subdue the criminal.
