HONG KONG, July 30 (Xinhua) -- A man was sentenced to nine years in prison on Friday in Hong Kong after being found guilty of inciting others to commit secession and engaging in terrorist activities.

Tong Ying-kit, 24, became the first person jailed for breaching the national security law in Hong Kong that took effect on June 30, 2020.

Tong rode a motorcycle with a flag bearing a "Hong Kong independence" slogan into police lines in Wan Chai on July 1, 2020, which caused serious injuries to three police officers.
