Police arrested two Germans on November 15 in Tuen Mun, New Territories, in a campaign to disperse protest groups gathered there.

The German consulate in Hong Kong contacted lawyers and local authorities to assist the captured citizens, a diplomatic source said, without elaborating. Bild newspaper reported that the two arrested were German students exchanged at Lingnan University, an art school with many students participating in demonstrations and violence.

Tensions in Hong Kong escalated after a college student died from a fall from an elevated parking lot near the police using tear gas to repel protesters. Hong Kong has been paralyzed for the past three consecutive days when protesters blocked roads and several subways.

Riot police had to use tear gas and rubber bullets to respond when students at Hong Kong Central University of China threw bricks, petrol bombs and set a fire. At the University of Hong Kong, students standing on overpasses throw chairs and other objects onto the road to obstruct traffic.

Hundreds of mainland Chinese students and trainees in Hong Kong pack their luggage and leave by pen, ferry or speedboat when violence strikes on campus. Many people plan to leave at the last minute for their own safety on the advice of friends, professors and administrators of Hong Kong. Some mainland Chinese students said they were surrounded and had to stay in dormitories, stockpiling instant noodles.

Violence alert authorities reach very dangerous levels, which can even lead to death. In the clash on November 13, 64 people were injured, two in critical condition. Chief Executive Hong Kong Special Administrative Region Carrie Lam called the protesters paralyzing Hong Kong "selfishers" and "enemies of the people".

Demonstrations in Hong Kong erupted in early June to protest the extradition bill that allows criminals to be sent to jurisdictions where the Special Zone has not signed an extradition treaty, including mainland China. The special zone authorities announced the withdrawal of the bill, but protesters still took to the streets with other claims, including the police's request to investigate the use of force and Lam to resign.
