A police search for a six-year-old girl who had been missing since Wednesday afternoon has ended after the girl was found safe on Thursday in another block of the estate where she lived. The girl, named Pinky Sze Wai-kiu, lives in Hong Ching House of Kowloon City’s Kai Ching Estate. She went downstairs in her school uniform to play at a park after school at around 4pm on Wednesday. The Kowloon Women's Welfare Club Li Ping Memorial School in Yau Ma Tei confirmed that the girl is a Primary Two pupil at the school. A staff member said police informed the school she had returned home after school yesterday afternoon and went out before she went missing. The staffer noted the school had set up a crisis management team to discuss how to address the situation. Unable to locate his daughter, the girl's father called the police for help at 3am on Thursday. The police searched overnight for the girl but to no avail. Around noon on Thursday, scores of officers from the Police Tactical Unit mounted a search with plainclothes and uniformed officers throughout the estate. In the afternoon, Sze was found safe in Mun Ching House, another block of the estate. At 2.30pm, police escorted a lady and a girl, the latter's face obscured by clothes covering it, away from Mun Ching House, leaving in a van. Police did not comment at the scene but earlier had said an investigation into the circumstances surrounding Sze's overnight disappearance was continuing. The initial investigation revealed that Sze met a seven-year-old girl at the Kai Ching Estate's playground. She followed her to her home in Mun Ching House, where she had dinner and slept overnight. The seven-year-old girl's father, 75, said that Sze told him: "I can't find my father. I'm hungry." At that point, he arranged for Sze to stay at the flat overnight with his daughter and foreign domestic helper. He went to work during the day and his daughter went to school, and Sze stayed at the flat with the helper, a police source said. The father called police "after he realised the girl was reported missing and police were searching for her" when he watched the news during his lunch hour, the source added. Officers went to the Mun Ching House flat to pick up the girl. She was inside with the elderly man and his helper. A police spokesman said no injuries were found on the girl and that the case was being treated as one of a "missing person located". Detectives from Sau Mau Ping district crime squad are investigating.
