A famous statue at the University of Hong Kong marking the Tiananmen Square massacre was removed late on Wednesday.
The statue showed piled-up corpses to commemorate the hundreds - possibly thousands - of pro-democracy protesters killed by Chinese authorities in 1989.
It was one of the few remaining public memorials in Hong Kong commemorating the incident.
Its removal comes as Beijing has increasingly been cracking down on political dissent in Hong Kong.
The city used to be one of few places in China that allowed public commemoration of the Tiananmen Square protests - a highly sensitive topic in the country.
In 1989, Beijing's Tiananmen Square became the focus for demonstrations calling for greater political freedoms. Thousands of people camped for weeks in the square, but in June the military moved in and troops opened fire.
