HONG KONG—A national-security crackdown in Hong Kong has extended to Facebook pages on which many workers and residents traded gossip.
Several prominent Facebook pages that were used to share anonymous comments about government and educational institutions in Hong Kong have shut down in recent days, following the arrest last week of two men by national-security police on suspicion of sedition. The men were administrators of a social-media group and suspected of publishing posts that “promote feelings of ill-will,” police said.
