Wong was arrested on 1 November 2020, along with six other democrats, in connection with the melee that had broken out in the LegCo on 8 May 2020. On that day,
Starry Lee, the incumbent chair of the House Committee of the Legislative Council, had attempted to commence a meeting of the committee after extended stalling tactics of the pan-democratic camp over the previous months. On 6 January 2021, Wong was among 53 members of the pro-democratic camp who were
arrested under the
national security law, specifically its provision regarding alleged subversion. The group stood accused of the organisation of and participation in unofficial primary elections held by the camp in July 2020. Wong was released on bail on 7 January. In late February 2021, after being charged with subversion, Wong was remanded in custody again along with other 46 activists and politicians. On 4 March, she was among only 15 of the 47 to be granted bail, however, she remained in custody pending an appeal by the Hong Kong government. Her bail application was later upheld by the High Court and she was released on bail. On 1 April 2021, High Court judge Esther Toh explained her rationale to release her on bail. Toh explained that Wong had not signed the declarations of hardcore democrats in maintaining the idea of, once elected, use the power of veto to block the budget and therefore force Chief Executive
Carrie Lam to give in to the five demands of the 2019 protests. Toh also highlighted occasions in which Wong voted in favour of government measures and policies and cited her low-risk to reoffend. However, Wong had to present herself before the court on 31 May 2021, when hearings on the subversion case resume. ==Personal life==
