Joshua Wong pleaded guilty in the District Court
Wong was arrested in January on suspicion of breaking the new law, which was introduced in July 2020
Wong was already in prison after he was found guilty of participating and organising an unauthorised assembly during the mass 2019 pro-democracy protests
Hong Kong democracy activist Joshua Wong was among four people who pleaded guilty on Friday (April 30) of participating in an illegal assembly on June 4 last year to commemorate the 1989 crackdown on protesters in and around Beijing`s Tiananmen Square.
It was the first time the vigil had been banned in the global financial hub, with police citing, as it did for all demonstrations last year, coronavirus restrictions on group gatherings. It is expected to face a similar fate this year.
