In 2019, following the proposal of the Fugitive Offenders Amendment Bill by the Hong Kong government, the Anti-Extradition Law Amendment Bill Movement was triggered, and violent protests erupted all over the city. On 6 August, the then president of Hong Kong Baptist University Students' Union Fong Zhong Xian was arrested by undercover police for possession of offensive or lethal weapons after buying laser pointers in Sham Shui Po. Responding to the arrest, Fong said that he was just buying the laser points for his friends and leaving one for himself for stargazing, and that when he was buying the laser points, he was not aware they could be used as a weapon.
