A performance artist on Wednesday sought to display a thin red thread in downtown Hong Kong to remember the victims of Beijing’s 1989 Tiananmen Square crackdown, 37 years on from the event. But he was quickly stopped by police, in the latest sign of the city's shrinking freedom of expression.
Sanmu Chen tried to tie the red thread to a street signpost in Causeway Bay, a busy shopping district, close to a park that for decades hosted an annual candlelight vigil on June 4 to mourn the victims of the crackdown that ended student-led protests in Beijing in 1989.
