Multiple news agencies have reported that people describing themselves to be Foxconn workers had pulled down barriers and faced off with hazmat-suited authorities at the Covid-hit plant.
The scuffles were broadcast live on the Kuaishou video platform, and videos showing hundreds of people coming face-to-face with others in hazmat suits, were seen on Twitter.
Other footage showed hundreds of workers marching on a road in daylight, with some being confronted by a row of people in hazmat suits and riot police. (Reuters/AFP)
