on 17 March and Leung Chai-yan said she had been "held against her will" at home. Chief Executive Leung Chun-ying declined to comment, apart from asking the public to "give her some room". A group of 10 college students organised a demonstration in support of Chai-yan and demanding government departments to take action against domestic violence. 2015 Halloween incident On 31 October 2015, Leung's daughter Leung Chai-yan celebrated Halloween at a number of nightclubs and parties in the Lan Kwai Fong area in Central and had a dispute with a taxi driver around 3 am on 1 November 2015. Her mother later arrived to the scene which enraged Leung Chai-yan. As Regina helped her daughter into the taxi, the latter was captured slapping Regina in the face twice, and her daughter refused to enter the vehicle. Regina was seen cradling her own cheek in shock.
