A teenager broke down in tears yesterday as she told a court how she was assaulted by a doctor during physical examinations in his clinic, where she worked as his assistant. The general practitioner, 56, who has a clinic in Causeway Bay, denied five counts of indecently assaulting his medical assistant between July 23 and August 1, 1998. He cannot be named for legal reasons. Eastern Court heard she was suspected to be suffering from vaginitis on July 23 and the doctor suggested a physical examination. When the prosecution asked the teenager, who was 17 at the time of the offences, to describe in detail how the examination was carried out, she broke down in tears and said: 'I don't want to talk about it. It is embarrassing.' Magistrate Timothy Casewell called for a short break and the court resumed after 10 minutes. The assistant told the court the doctor had interfered with her private parts for two to three minutes during two examinations. She had a similar examination a few days later. 'On a day I forget when, I told the doctor there was acne on my chest and back. He unbuttoned my uniform, stroked my back, and fondled my breast. The acne was not on my breast but my chest,' she said. The alleged victim said that on August 1 she and her colleague were talking about having to go on a diet when the doctor overheard their conversation. 'My colleague happened to go away to answer a telephone call. The doctor asked me if I did need to go on diet. 'He then put his hands on my armpits and slide them down to my buttock, and suddenly grabbed my breast, saying that there wouldn't be anything left there [if I lost weight],' the teenager said. After her parents were told of the incident, police were called. 'I called back to the clinic and told my colleague what happened that day. I quit working there because I found the doctor to be a pervert,' she said. Lawrence Lok SC, defending, asked the former medical assistant why she called the police. She replied: 'I wanted to punish him, so that he will never have a second chance to harass other girls.' She disagreed with Mr Lok's suggestion that instead of fondling her breast, the doctor was actually teaching her how to examine it, because she had allegedly told the doctor that her breast was painful. The hearing continues.
