A police graphic says protesters are 'silencing voices' and 'threatening people who hold different opinions'.

The Hong Kong Police Force accused the city's protesters of using "so-called democratic ideals" as an excuse to silence their opponents, RTHK reports.

On social media, they declared that "innocent" Hong Kong people have had enough of the "havoc" protesters are causing.

The strong comments on Twitter followed a post by the force referring to an incident at the New Town Plaza shopping centre on Sunday, when a crowd surrounded a woman who was taking photographs of protesters.

"On 15 December, a lady was surrounded and had her phone snatched by rioters who held dissenting views only because she had taken photos of them. Her phone was smashed in the end!", the police wrote.

"Innocent citizens have had enough! We’ve seen many reports of rioters taking the law into their own hands and wreaking havoc across the city. The so-called democratic ideals are just cover-ups for silencing all other voices," the force added.

The post also came with a graphic showing two male characters wearing black clothes and face masks squaring off against a female character holding a smashed mobile phone.

Captions read "Silencing voices!" and "Threatening people who hold different opinions.''
