Taiwan-based Foxconn Technology, a major supplier for Apple, has halted production at a plant in northern China after a fight broke out among workers.
Foxconn confirmed that a "personal dispute" escalated into an incident involving about 2,000 workers, injuring 40 of them. Police later dealt with the situation near the facility in Taiyuan, which employs about 79,000 workers.
Foxconn has previously been accused of having poor conditions for its workers.
