Hong Kong authorities cordon off the Hong Kong Polytechnic University in the latest standoff between anti-government protesters and police forces.
Hong Kong police fired rubber bullets, tear gas, and cannons on Monday to keep the demonstrators inside the campus.
Students have reportedly tried fleeing the campus but have been stopped by the tear gas and other tactics repeatedly, which has forced them back inside.
Some were arrested as they tried to escape, and others were tackled to the ground amid the ongoing standoff.
Authorities claim they were sent to the campus in an effort to entice the rioters to leave the area.
This escalation comes on the heels of a violent weekend, which ended with 154 people being arrested.
Meanwhile, university students were urged to flee Hong Kong last week as protests continue to violently escalate, just days after a student died of protest-related injuries.
Students from China, Taiwan, and three Scandinavian countries were urged to leave Hong Kong as the ongoing demonstrations continue to plague campuses in the area.
Reuters reports students were stockpiling food and weapons on last week while also constructing barricades around universities.
Around 1,000 demonstrators reportedly took to the streets blocking roads in the Central District, which prompted a swift police response involving both an armored vehicle and less-than-lethal ammunition.
Protests originally erupted back in June over an extradition bill, which has since been taken off the table.
Those rallying against the measure were worried individuals who would be extradited to China could face torture and unfair trials.
Since then, the months-long protests have gradually evolved into wider calls for democracy, including probes into alleged police brutality and even the Carrie Lam’s resignation.
