Badminton player Issara Chasing was caught on video chasing down and pummeling his former olympic teammate Maneepong Jongjit during the 2013 Canada Open. The New York Daily News says the two were disqualified as a result but no charges were filed. Huffington Post reports there was no immediate cause of the fight but it might have had something to do with bad blood simmering between the two since Jongjit announced his retirement, then started playing with a new partner.
