Hong Kong actor Eric Tsang was accused of raping artistes, Sin Chew Daily reported.
Grace Han, the former Asia-Pacific head of Ford Models, wrote on her Weibo account that her student nearly fell into the trap of Tsang and his friends in Hong Kong.
She claimed that Tsang had spiked the beverages of models at a KTV club, but luckily one of her students was alert and escaped unscathed.
In the follow-up posts, Han stood by her allegation, adding that she would reveal the names of other men present that night.
In a separate incident, Tsang said a video that named him as one of two male stars who raped actress Yammie Lam was fake news.
In a statement issued on Wednesday, he said the clip of an interview with Lam that surfaced on the Chinese Internet site was falsely edited, reported Phoenix TV's iFeng website.
Tsang, 64, said he had engaged a law firm to take action against the video.
