Hong Kong’s summer of protests is now stretching into the fall. Clashes between demonstrators and police have often become violent. But medical workers have quietly joined to form the Hidden Clinic and other groups to help injured protesters. The groups secretly treat young demonstrators who fear arrest if they go to government hospitals. One person recently contacted the Hidden Clinic through the social media service Telegram. The person wanted to find help for a friend who appeared to have a broken arm, the group told The Associated Press, or AP. The person explained their injured friend’s concerns about arrest, saying, “Many of his friends have been detained when seeing doctors.” The Hidden Clinic claims to have treated 300 to 400 protesters with many injuries.
