Protesters demanding the resignation of Hong Kong's chief executive have clashed with riot police in a mainland shopping centre in Sha Tin.
Footage shows officers appearing to strike demonstrators with batons after more than 10,000 people marched for greater democracy in the territory.
Protesters also called for an investigation into complaints of police violence.
The demonstrations that began at around 3.00pm in the northern Hong Kong district of Sha Tin were peaceful throughout most of the day.
Scuffles broke out after nightfall when police started clearing the streets in the densely crowded area of high-rise buildings.
Hundreds of protesters, many wearing helmets and surgical masks, retreated into a shopping complex where some threw umbrellas and water bottles at police.

The two sides were later seen along the walkways of several floors of the complex hitting each other with umbrellas and grabbing each other's helmets.
Many also fled the scene on near-by trains, with journalist Aaron Mc Nicholas saying the railway operator had waived the fares.
