A disturbing video has surfaced showing radical 'Antifa' members bullying a disabled man in a wheelchair this past weekend in Berkeley, California.

The video shows a motorcycle helmet-wearing left-wing activist taking the disabled man's water bottle and pouring it over him. Others heckle him, while some try to put a halt to the abuse.

Members of the anarchist 'Antifa' had descended onto a park in Berkeley in order to stop a 'No to Marxism' rally.
