Hong Kong protesters held a vigil for “martyrs” on Saturday and many demanded “revenge” after a student died in hospital this week following a high fall, fuelling anger among pro-democracy demonstrators who first took to the streets in June.

Thousands of people peacefully gathered in Tamar Park next to central government offices in the former British colony that returned to Chinese rule in 1997, after they had secured rare permission from the police to hold the evening rally.

The protesters sang hymns and carried flowers, while many shouted “revenge,” a call heard increasingly often at rallies and given added impetus since a student died on Friday after falling from a multi-storey car park during a protest.

Police estimated 7,500 people attended Saturday’s vigil.

“Tonight we are not only here to mourn for him but to show the government, the Chinese Communist Party and the world that the things that have happened in the last six months have not been forgotten,” said Tom, 26, a government worker who asked that only his first name be used.

Chow Tsz-lok, 22, a student at Hong Kong’s University of Science and Technology (UST), fell on Monday as protesters were being dispersed by police.

Seven Hong Kong pro-democracy lawmakers were either detained or faced arrest on Saturday, a move that could escalate public fury a day after the death of a university student linked to months of anti-government protests in the semi-autonomous Chinese territory.

Protesters vented their anger over Chow Tsz-Lok’s death and vowed not to give up their resistance at a police-approved prayer rally Saturday night, with frequent chants of “Hong Kong people, revenge” and “Free Hong Kong.” The 22-year-old died Friday, succumbing to injuries four days after falling from a parking garage when police fired tear gas during clashes with protesters. Although the circumstance of his death is unclear, many blame police who have been accused of heavy-handed tactics including widespread use of tear gas and pepper spray since the unrest began in June.

Police said three lawmakers were detained Saturday and charged with obstructing the local assembly during a raucous May 11 meeting over a now-shelved China extradition bill that sparked five months of protests calling for democratic reforms.

The others received summons to turn up at police stations Saturday to face arrest. All seven are to appear in court Monday.

Pro-democracy lawmakers slammed the government clampdown as a calculated move after Chow’s death to provoke more violence as an excuse to postpone or cancel Nov. 24 district elections - polls viewed as a barometer of public sentiment amid the unrest.

Rallies have often erupted into clashes between police and protesters, creating the worst political crisis in the territory for decades, although Saturday’s vigil that drew students, older people and a few children was quiet in the early evening.

Police said they had fired one round of live ammunition on Friday as a warning to what they described as “a large group of rioters armed with offensive weapons” who threw bricks at officers trying to clear street barricades in the Kowloon area.

“The lives of the officers were under serious threat,” police said in the statement, released on Saturday.

Students and young people have been at the forefront of the hundreds of thousands who have taken to the streets to seek greater democracy, among other demands, and rally against perceived Chinese meddling in the Asian financial hub.

China denies interfering in Hong Kong and has blamed Western countries for stirring up trouble.

Under China’s “one country, two systems” formula, Hong Kong has retained freedoms from the colonial era not enjoyed on the mainland, including an independent judiciary and the right to protest.

“We believe that the government together with the police, as well as the pro-establishment camp, they are trying to escalate the anger of Hong Kong people in order to cancel or even to postpone the upcoming district council election,” Tanya Chan, a pro-democracy lawmaker, said at a press briefing, referring to upcoming elections on November 24.
