Figo Chan, a convenor of the now defunct Civil Human Rights Front, was given the toughest sentence for playing a leading role in the July 1 protest, the Hong Kong broadcaster RTHK said.

Former lawmaker Wu Chi-wai and ex-district councilor Tsang Kin-shing were each handed a 10-month jail term, given their social status, while the rest received six to eight months.

The illegal demonstration was called a day after China imposed security rules on the former British colony to punish subversion, secession and terrorism. It coincided with the 23rd anniversary of Hong Kong’s handover.
