Some still clutched umbrellas and masks that they had used to fend off tear gas lobbed by police in a failed attempt to disperse them.
The overnight clashes between thousands of protesters and police marked the latest escalation in the battle between Hong Kong’s pro-democracy activists and the territory’s rulers in Beijing.
In recent weeks, the democracy movement had appeared to be flagging after a summer of simmering dissent. But this past week, a boycott by students galvanized the cause over the weekend and prompted thousands to join the students’ nonviolent siege of Hong Kong’s government headquarters.
Their protests yielded scenes of unusual chaos over the weekend in the usually staid Asian financial hub.
