A day after thousands of civil servants took to the streets in Central to urge authorities to give in to the protesters' demands, people gathered on August 3 for an approved rally in the shopping hub of Mong Kok.  The march soon splintered and ended with clashes in Mong Kok, Tsim Sha Tsui and Wong Tai Sin, where police used tear gas. Earlier, a group of protesters blocked the Cross-Harbour Tunnel twice, bringing traffic to a standstill.
