Pro-democracy lawmakers handed themselves in to police yesterday over their involvement in the Occupy Central protests. This is a controversial process which some say is a form of harassment.
Police have vowed to investigate the "principal instigators" of last year's pro-democracy protests.
Albert Ho Chun-yan and Helena Wong Pik-wan, both of the Democratic Party, turned themselves in to Wan Chai police headquarters on Monday morning after being requested to attend. Each of them was holding a small, yellow paper umbrella - the symbol of the movement - in the air, as supporters shouted: "We want universal suffrage."
"We Hongkongers who have tried to fight for true democracy are not the ones who have done something wrong … it is the ridiculous Hong Kong and Chinese governments taking away our democratic nominations," Wong said before she went inside.
The protests that began in September and lasted for more than two months began after Beijing ruled that candidates for Hong Kong's next chief executive must be approved by a pro-Beijing nominating committee.
Protesters dismiss that as "fake democracy", but the government says any public vote must take place within Beijing's framework.
Prominent student leaders, including Joshua Wong Chi-fung, have already been through the police procedure, which saw them formally arrested and questioned when they handed themselves in, then released without charge hours later.
Some Occupy leaders have questioned the process, saying police should charge them if they had the evidence.
"The police are trying to intimidate Hong Kong people," said former lawmaker Audrey Eu, who was brought in for inciting and organising an unauthorised assembly.
Ho, Helena Wong and Eu were all released yesterday afternoon without being charged.
Police said they reserved the right to prosecute those who were released.
