Hong Kong demonstrators marked an annual festival by gathering at local police stations to denounce the heavy-handed tactics officers used against protesters at the city’s international airport over the weekend.

Activists aimed laser pointers at a police station and chanted “an eye for an eye,” a reference to the woman who suffered a severe eye injury after being shot with a beanbag gun at close range. Police fired tear gas at the assembly, but protesters returned to the site about an hour later while leading activists called for international support.
