A minibus driver was detained after scattering threaded nails on a road in China. The CCTV video, captured in Shanghai on March 21, shows a minibus stopped in the middle of a road on an overpass and the driver scattering the nails across the road. According to reports, a police officer stopped a minibus and penalised the driver as the vehicle loaded goods illegally. The 45-year old driver named Sun then got emotional and took a box of threaded nails out of his minibus to scatter them onto the road. Sun has been detained and the case is under further investigation. The video was provided by local media with permission.
