Wong, Lam and Chow, who were leaders and members of the disbanded Demosisto, a pro-democracy group advocating the city's independence, were sentenced on Wednesday, Xinhua news agency.

They three have been accused of inciting others to participate in an unauthorized assembly, organizing an unauthorized assembly, and knowingly taking part in an unauthorized assembly.
