A doctor accused of molesting three nurses exposed himself to one of them after asking her to help him secure his trousers because he did not know how to use a safety pin, a court heard yesterday. Dr Allan So Cheuk-wai, 35, of Queen Elizabeth Hospital, faces five counts of indecent assault, three counts of committing an act outraging public decency and one count of indecency. He is accused of sexually assaulting three nurses and exposing himself to a 20-year-old student near his home in Hung Hom. The 35-year-old nurse who described the safety pin incident testified in Kowloon City Court yesterday that she was attacked twice within about six months in 2010. She broke down in tears at one point. Under questioning by prosecutor Jonathan Man, the nurse said she and So were sitting next to each other at a nursing station in the summer of 2010 when he asked her if his trousers looked loose. She told him they did because she could see the waistband of his underpants and went to her locker to fetch some safety pins as So requested. She said So had asked her to teach him how to use the pins and opened the door to a nurses' rest room. Inside, she used her coat to demonstrate. So had then asked her whether he had done it properly, and looked down. 'Then I saw his pubic hair and his penis,' she said. 'I immediately stood up straight and I was very frightened.' A health care assistant sitting across from So asked the woman what was taking so long. She replied: 'You help him, then,' and left. The witness said she was also molested by So in January that year as she helped him treat a patient. So walked behind her and she felt his genitals pressing against her left buttock. He then pressed against her again. She said she knew 'the hard object' could not have been a mobile phone because she was an experienced nurse and had been married for many years. So did not say 'excuse me' or apologise to her after the touching, she said. The object could not have been any of So's personal belongings since they were all in his white coat, which he had taken off. She wept when So's lawyer, Graham Harris SC, asked if it was the first time she had told anybody about So's white coat, as it did not appear in her witness statement to the police. The case adjourned for 10 minutes to let the nurse recover. She said she had reported the incidents to her superiors only after hearing about similar incidents from two other nurses. 'I felt this was very scary,' she said. She was transferred to Princess Margaret Hospital, where she called police after hearing what had happened to a 41-year-old nurse in June last year. That alleged victim also testified yesterday, saying she had seen a psychologist at least four times since the incidents. The hearing continues today before Deputy Magistrate Ko Wai-hung.
