Hong Kong police fired tear gas on Tuesday at a group of pro-democracy protesters rallying outside a police station in a crowded urban neighborhood.
The protesters had gathered to burn "hell money" and incense as a way to show their opposition to the police during the month-long Hungry Ghost Festival, when offerings are made to ward off spirits of ancestors.
Last week, the Sham Shui Po district was the scene of a protest against police after they arrested a university student leader for buying laser pointers, which police said were being used as a weapon against them.
Some protesters were seen pointing these laser lights on the exterior of the local police station to protest against the arrest.
Police armed with riot shields and batons marched down streets in the blue-collar neighbourhood.
Officers carried warning flags and fired tear gas as they advanced, but protesters had already scrambled away.
