For the seventh consecutive weekend, protesters in Hong Kong gathered on Sunday to demand an independent investigation into excessive police force used during previous demonstrations against the controversial extradition bill.
They also demanded the release of protesters who were arrested during previous protests.
Protesters marched towards the Liaison Office, which represents China's Communist Party-led central government within the city.
They threw eggs and splattered black ink on China's national emblem in the front of the Liaison Office.
Police responded by using tear gas to disperse the crowd.
According to organizers, 430-thousand people participated in Sunday's march.
