Hong Kong's incoming leader Leung Chun-ying observed a minute's silence Saturday in memory of Chinese dissident Li Wangyang in the latest display of concern in the southern Chinese city over his death.
The tribute to Li, who was jailed for more than 22 years after the 1989 Tiananmen democracy protests and died earlier this month at a hospital in central China, took place in the Asian financial centre.
It came after a huge march in Hong Kong demanding answers about his death last weekend, and after a senior official in the city said the death was suspicious.
According to New York-based group Human Rights in China, two of Li's relatives found him strung up to a windowsill by a bandage wrapped around his neck, with his feet on the ground.
The nearly deaf and blind democracy activist was under round-the-clock police surveillance at a hospital when he died, the group said.
Leung, who will start his term as the southern Chinese city's chief executive next month, had been criticised for dodging questions about the death.
Earlier this week, he said that his personal feelings about Li's death were the same as those of the Hong Kong people.
Hong Kong Food and Health Secretary York Chow said earlier this week that he doubted Li had hanged himself.
