The last remaining memorial to the Tiananmen Square massacre in Hong Kong was covered up on Saturday.
The memorial — calligraphy painted on the roadway — commemorated the hundreds or thousands of protesters who were killed by the Chinese government in 1989, according to the BBC.
University of Hong Kong workers covered the calligraphy with yellow and black striped metal safety plates, and claimed the action was regular maintenance, the outlet reported.
The calligraphy was repainted every year since the massacre.
Hong Kong, a special administrative region which traditionally enjoyed more political liberty than mainland China, had been a rare place in China where public monuments and discussions about the heavily-censored “June Fourth Incident” were allowed.
China has been increasingly tightening speech controls in Hong Kong.
In January, an activist was jailed after organizing a Tiananmen Square vigil. Authorities banned the vigil for the past two years, blaming the pandemic.
