In November 2019, protesters occupied the university as part of the 2019 Hong Kong protests. Students fought with the Hong Kong Police Force from 17 November to 19 November. On November 16th, police tried to enter the campus, but protesters kept them out with road blocks and petrol bombs. The police then blocked all exits from the university campus and asked all protesters inside to give up and come out. On November 18, the police shot 1,491 canisters of tear gas at protesters and shot 1,981 rubber bullets, bean bags, and sponge grenades. The university has been called a battleground. The university was later closed off by police, but protesters still escaped. More than 280 protesters were injured and more than 1,000 people were arrested.
