Foxconn Technology, a major supplier for Apple, has halted production at a plant in northern China after a fight broke out - apparently in a workers' dormitory.
Foxconn confirmed that a "personal dispute" escalated into an incident involving about 2,000 workers, injuring 40 of them.
However, comments on a Chinese microblogging site suggested the fight broke out after security guards beat a worker.
Foxconn has previously been accused of having poor conditions for its workers.
