Hong Kong actor Eric Tsang (曾志伟) was arrested on Wednesday for allegedly assaulting restaurant owner Kenny Wong (黄浩) early this month.
Eric was released on bail later the same day.
The 59-year-old has been charged with common assault and criminal intimidation and has to report to the police in January.
Eric reportedly slapped Kenny, husband of actress Suki Chui (徐淑敏), around the face when they met at a wedding banquet earlier this month.
Eric was furious that Kenny had claimed he had video evidence of some HK celebrities using drugs in his restaurant.
Kenny reported he has been threatened by gangsters several times to keep mom on the matter.
Singer Eason Chan‘s (陈奕迅) wife Hilary Tsui (徐濠萦) and Josie Ho (何超仪), who is daughter of Macao casino magnate Stanley Ho (何鸿燊), are suspected of using drugs at a birthday celebration in Kenny’s restaurant in October 2011.
