Special duties constable Ho Kit-ying did not imagine she would be thrust onto the frontline in the fight against crime when she joined the police force. But the 30-year-old who has worked out of Cheung Sha Wan Police Station for 10 years now says she will be a crime-fighter for the rest of her career. She was born into a police family, although her father left the force after two years in the 1970s because her mother was concerned about his safety. 'He liked the job very much and urged me to join the police. He hoped I could continue the job he started,' she said. 'I was too young to make a choice myself. My family thought society at that time was not as threatening as it was in the 1970s, and I guessed that not all police work was dangerous - maybe I would have an office job dealing with citizens' complaints.' But Constable Ho faces danger almost every day as she arrests prostitutes and drug addicts in Shamshuipo, a notoriously crime-ridden area of Kowloon. She said police had to be constantly alert when confronting such criminals. 'Some addicts may lose control and use dirty syringes to attack police,' she said, adding that body-searching prostitutes was far from pleasant. 'Many prostitutes keep knives and cutters in their bras. Some hate the police and try to bite you. It's quite dangerous.' One part of the job she particularly enjoys is surveillance - trying to identify drug traffickers and prostitutes soliciting customers. 'It's just like a cat-and-mouse game,' she said. Tanned and athletic, Constable Ho attributes her discipline to her participation in adventure races. A past champion of the Hong Kong Trailwalker event, she won this year's Action Asia Challenge, an adventure racing series that tests the skills of weekend warriors. 'If I had not developed strong mental strength during the harsh exercise that takes up my spare time I might have already quit my present job, which can drag on over 12 hours a day,' she said. Constable Ho will be the only woman in the team representing Hong Kong in the Mild Seven Outdoor Quest in Sabah, Malaysian Borneo, which starts on Thursday. She will cover 300km in a four-day race involving seven sports including mountain biking and kayaking. Constable Ho said the team's aim was to complete the contest, hailed as 'the world championship of multi-sports'. 'There are many risks. Heatstroke and injuries are common. Many competitors have given up in the past. But I want the challenge; I want to see where the bottom line of my strength is,' she said.
