Hundreds of riot police and geared-up protesters faced off each other after a handful of protesters broke several glass doors of the Legislative Council in an attempt to enter the building early Wednesday, following the execution of a court order to remove some roadblocks nearby that were part of a pro-democracy occupation campaign.

Protesters with helmets, eye goggles and face masks brandished umbrellas and occasionally clashed with police standing guard outside the legislature building in riot gear, according to local media TVB footage.

Police used pepper spray to disperse a few protesters who threw rocks and charged at the building with metal barricades shortly after midnight, it was reported.

The patience of some protesters was apparently wearing thin as the occupation campaign, entering its 53rd day, has yet to force the authorities for a change in the territory's leadership election in 2017.

Most of the roadblocks at car entrances and emergency exits of a commercial building in Admiralty, the main occupation site where the government headquarters is located, were removed under the watch of court bailiffs Tuesday as instructed by an injunction.

Two other injunctions targeting barricades set up in shopping district Mongkok are expected to be executed later in the week.

Hundreds of protesters have been camping out on major roads in sections of the territory since Sept. 28 after the Chinese government in August decided that candidates for the leadership race must be screened by a nominating committee to qualify to run.

The pro-democracy camp has denounced the procedure as "sham" democracy.
