Netizens initiated a "Shop with you" at Tai Po Mega City this afternoon. During the riot police's dispersion operation, two plainclothes police officers were suspected to be demonstrators and they were tied around the neck and pushed to the wall uniforms outside the mall. They were later being recognized as "[their] own people", and were released. Many people were arrested in the vicinity of the shopping mall. Police officers were suspected to have deployed pepper spray and blue dye in the shopping mall. Some elderly people had their faces stained blue due to the blue dye.
