Four Scholarism members, including convenor Joshua Wong Chi-fung, were released without charge this afternoon after reporting to Wan Chai police station over their role in Occupy Central protests. Wong was released after three hours although police told him that he had been arrested on the suspicion of inciting, convening and participating in unauthorised assemblies. He said he refused to be bound by bail. He said that during questioning, police showed him 17 video clips from YouTube and news reports in which he appeared. He remained silent throughout the process. Scholarism members Agnes Chow Ting, Oscar Lai Man-lok and Derek Lam Shun-hin were also released without charge. A police spokesman confirmed on Friday evening that Wong and the three other Scholarism members were arrested on the grounds Wong described, and added that police would “reserve the right to prosecute”, despite their immediate release. Wong, now a first year student at the Open University, said before entering the police station that he was not nervous as he had been arrested several times before. The four students are the latest group invited to “assist investigations” over the 79-day Occupy Central movement that brought many of the city’s major roads to a standstill. In the past few days, activists and politicians have been going to the police station for the same purpose. Most of them have remained silent in the process and refused to be bound by police bail. Some of them were told by police that they were accused of inciting, organising and participating in unlawful assembly. They were released without charge but it is not clear whether police will go after them again in future. Earlier, Wong suggested that the Scholarism members would all remain silent when questioned by police.
