Suspected triad members are among seven people arrested over scuffles that broke out between pro- and anti-government camps outside a Tin Shui Wai event attended by Chief Executive Leung Chun-ying on Sunday.
The trio were suspected to belong to triads active in Tuen Mun and Yuen Long, a police source close to the matter said. Officers were looking for the fourth man, aged between 20 and 25, and any co-conspirators behind the assault.
Political scientist Ma Ngok, of Chinese University, criticised the possible triad link. "Leung's administration is acting like other dictatorial regimes around the world that hire triad members to attack dissidents."
