HONG KONG - Actor Francis Ng blew up and threw a microphone during an interview in China on Tuesday, when he spoke of how Hunan TV has not taken responsibility for an injury his son sustained in connection with a reality show, said Ming Pao Daily News.

Ng and Feynman, his son with former Singaporean actress Ong Lay Pheng, had joined the second season of Where Are We Going? Dad last year and travelled to New Zealand for a shoot.

There, the boy sustained a wound to the corner of his left eye and needed two stitches. Afterwards, Ng said his son had blurred vision and they quit the shoot of the show's big-screen spin-off.

Before his interview on Tuesday, Ng received news that his son's vision was diagnosed as permanently damaged, said Ming Pao.

In a video of the interview that turned up online on Wednesday, Ng is seen saying: "I'd like to ask, does it feel good bullying a child? A six-year-old child is injured and his insurance hasn't been handled. Must we really see you in court?"

Later in the video, after saying the damage to his son's eye is "permanent", he is seen throwing the microphone and leaving.

At the time of Feynman's injury, producer Xie Dikui said the boy had been playing with other celebrities' children when he fell and hit the stairs. Xie said there was no footage of the incident as the children were not being filmed then.

On Wednesday, the show said it could not comment as its producers were in Shaanxi shooting a new season and the signal was too bad there for them to watch Ng's interview. Yesterday, Xie wrote on Weibo: "Truth will out," in an apparent response to Ng's remarks, said NetEase website.
