HONG KONG: A Hong Kong student who helped found a network of volunteer medics to aid the city’s pro-democracy protests has been arrested on the mainland, fellow students briefed by his university have told AFP. Classmates say Kwok Chun-fung has been detained on charges of “soliciting prostitutes” in Guangzhou, the capital of the Chinese mainland province that borders Hong Kong. The same allegation was brought against Simon Cheng, a Hong Kong employee of the British consulate who was detained during a trip to the mainland in August last year. After his release, Cheng said he had been forced to confess before fleeing overseas. Kwok, who is in his early twenties and studies in Guangzhou, co-founded a volunteer group that helped wounded protesters and those affected by police tear gas during the seven months of unrest that has engulfed Hong Kong.
