Riot at Foxconn factory in China blamed on harsh security guards

Foxconn workers are blaming company security guards for Sunday's unrest at a manufacturing facility in China, claiming that the mass riot was the result of an escalating brawl between assembly line workers and security guards.

The riot, which involved 2,000 workers, occurred at a Foxconn factory in the Chinese city of Taiyuan and sent 40 people to the hospital before it was quelled by local police. While Foxconn said the incident arose from a "personal dispute," without elaborating, company workers interviewed on Tuesday said the riot first started as a fight between only a few security guards and workers.

Although it's unclear what exactly sparked the fight, workers said it's well-known that Foxconn security guards are often domineering and aggressive toward assembly-line workers. The unrest also came as workers from Foxconn's other manufacturing facilities in China have been transferred to the Taiyuan facility to learn how to assemble Apple's iPhone 5.
