Foxconn, the company that makes Apple iPhones, suspended production at a factory in China on Monday after a massive brawl involving as many as 2,000 workers.
The brawl reportedly started because of a "personal dispute" between workers from two Chinese provinces, Shandong and Henan, Time wrote.
After it spilled out from a worker's dormitory and led to 40 people being injured, 5,000 security officers swarmed the scene, according to reports, citing the company.
The dormitory was near a Foxconn Technology Group factory in the northern city of Taiyuan, Newsday reported, citing the company and Chinese police.
However, postings on a Chinese microblogging site, cited by the BBC, suggested that the fight broke out after security guards beat a worker.
Taiwanese-owned Foxconn — which employs around 1 million people across China — has drawn negative publicity in the past over poor conditions for its workers.
The company said the facility, which employs 79,000 people, would reopen Tuesday.
It did not say whether the factory was involved in iPhone production.
