On Thursday, a former spokeswoman of the pro-democracy student activist group Scholarism, Prince Wong Ji-yuet, and 13 others were sentenced to prison for their involvement in the Polytechnic University siege during the social unrest in 2019
The District Court handed down a sentence of three to four years and four months to Wong, who pleaded guilty, and reduced her jail term to 37 months due to her volunteer work and contributions to society.
The court also noted that Wong had been studying art therapy while in custody.
The 14 defendants, who took part in the "rescue protests" outside the Polytechnic University, were found guilty of carefully crafted acts of violence that would never be tolerated.
The court said that the number of participants once reached 2,000 and it was lucky that there were not many casualties.
The remaining 14 defendants were sentenced to between three years and three years and five months in prison after being convicted of rioting.
Yan Nim-yin, who was only 16 at the time, was sent to a training center.
The Polytechnic University siege was a series of protests and violent clashes between pro-democracy activists and police that began in November 2019.
The protests were sparked by a proposed amendment to the Fugitive Offenders Ordinance that would allow for the extradition of fugitives to mainland China.
The protests eventually escalated into a wider movement for democratic reform in Hong Kong.
