Martin Lee Ka-shing, co-chairman of Henderson Land, has initiated legal proceedings at the High Court against actress Chrissie Chau, five YouTube channels and Google LLC.
Chrissie Chau responded on social media, expressing surprise at being sued.
She emphasized that she does not know Lee and she's feeling wronged by his accusation.
In a personal statement, Lee said he is suing Chau for defamation and harassment, alleging that she sparked false rumours about him.
He stressed that he does not know Chau and has no relationship with her.
At the same time, Lee is also suing the five YouTube channels and Google LLC, saying he hopes to curb what he described as an unchecked culture of online bullying.
