HONG KONG: Hong Kong student leader Joshua Wong was found guilty on Thursday of participating in a protest that led to mass pro-democracy rallies, in a prosecution blasted as a “chilling warning” by rights campaigners. The verdict comes as tensions remain high in the semi-autonomous city with fears growing that Beijing is tightening its grip. Wong has always said the various protest-related cases against him were political persecution. Rights group Amnesty International described cases against peaceful protesters as intimidation Thursday in the wake of the verdict. Wong was convicted for taking part in an unlawful assembly after he and other students climbed over a fence into a Hong Kong government complex forecourt known as Civic Square, on Sept. 26, 2014.
