A huge sinkhole opened up on Monday evening in the city of Shenzhen, Guangdong Province, killing at least five men.
The 10-meter-wide chasm formed near the gates of Huamao Industrial Park, when many factory workers were changing shifts, according to the Guangming Daily.
Local authorities have so far identified four of the five people who died, and another man who fell in was rescued, the Global Times reported.
Rescue workers were uncertain as to how many people had been pulled into the sinkhole, but continued their search the next day, according to the South China Morning Post.
Internet users are questioning the safety of local constructions, as this is the third sinkhole in the area in only two months.
In March, a Shenzhen security guard was killed when a sinkhole suddenly opened up that was 12 meters deep. In April, an 8-meter-deep sinkhole formed in the city, but reportedly no one was hurt.
Many people think the sinkholes in China are caused by construction or other man-made developments. According to the U.S. Geological Survey, the holes may form due to groundwater pumping or other changes in the natural water-drainage system.
