Hui and Wong were caught on camera holding hands and kissing in the back seat of a taxi, in a scandal that broke on Tuesday (April 16). Hui has been married to singer-actress Sammi Cheng since around 2014.
According to Hong Kong media reports, the entire video clip was sold by the driver of the taxi to the media for about HK$1.5 million (S$258,700). The exclusive video clip was released by Apple Daily on Tuesday, and media reports said there are two other video clips which have not been released.
Meanwhile, Hui's manager Paco Wong has confirmed that Hui's planned concerts in Hong Kong in September have been cancelled as the singer has been emotionally affected by the incident.
Besides the concerts, Hui has other performances and shows scheduled in China. Asked about the financial losses due to these cancellations, Mr Wong said: "It's not an issue of money. I hope there is no need for compensation."
As for Cheng's planned concerts in Hong Kong in July, there is so far no word on whether they will be affected by the scandal.
There are reports that Cheng has moved out of her apartment as she does not want to live with Hui after the scandal broke. But an Apple Daily report said that Cheng has not moved out and that Hui had apologised profusely to her after going back to their home after his press conference on Tuesday evening.
Talk of more video clips surfaced after Apple Daily released on Wednesday a more complete version of the first video clip, which showed Hui and Wong leaving the taxi together after reaching her home.
A man who was shown in the video clip with Hui and Wong has been identified by Apple Daily as Mr Kenneth Yang, a senior executive at an insurance company. He is a good friend of both Hui and Cheng.
According to Hong Kong media reports, the couple had celebrated Mr Yang's birthday two days before the incident, but Hui and actress Wong gathered a group of friends two days later to celebrate Mr Yang's birthday again.
Mr Yang noticed that Hui and Wong were behaving suspiciously after the celebration ended, and in the taxi, offered to drop Wong off first at her home. However, she rejected his suggestion and insisted that Mr Yang alight first. After a round of argument, Hui took Wong's side and assured Mr Yang that he and Wong would go home separately.
After Mr Yang alighted, both Hui and Wong told the driver to head to Wong's home in Lei Yue Mun. They held hands and Wong kissed Hui numerous times in the car.
Hui was also seen to be sitting in a low position in the taxi as if he did not want to be seen by people in other cars. The video clip showed them alighting together.
