A totally insane Monday in Hong Kong has unsurprisingly bled into Tuesday with protests raging on across the city, turning university campuses into battlegrounds.

The Chinese University of Hong Kong (CUHK) has been the scene of continued clashes between student protesters and police throughout the day. To stop officers from coming in, students erected barricades around campus, even setting one van on fire.

In an attempt to disperse the protesters, police have fired tear gas on campus. Clips from the prestigious university show it looking more like a war zone.

Due to safety concerns, all classes at CUHK were canceled on Tuesday and won’t resume on Wednesday. A number of other schools and universities in the city have also followed suit including Hong Kong Polytechnic University.

At Polytechnic, student protesters looked to disrupt traffic near campus, throwing trash cans and other debris from an overpass onto a road below:

Though the demonstrations haven’t been confined to just the university campuses. At noon, more than a thousand protesters flooded Central in a flash mob protest, blocking traffic in Hong Kong’s business district during lunchtime.

Following the break, hundreds of them have also stuck around.

This is the second day in a row Central workers have used their lunch break to come out like this while frontliners create defensive barriers.

Meanwhile, many workers had a hard time getting to work in the morning with widespread road closures and suspended railway services as protesters even threw debris onto MTR tracks.

Inside metro stations, long lines formed as police searched and questioned commuters.

Police at Tiu Keng Leng are asking people, one by one, if they are responding to online calls to participate in the traffic disruption. The police told this man to watch the news from home if he only wants to watch the force take action.
