Victim offered 'magic sword'
A friend who had been playing swords with the murdered five-year-old boy found in a nylon bag on Saturday has become the key witness in the investigation.
Yu Chi-fung's playmate told police yesterday he had been with Chi-fung the day he was killed.
Chi-fung was found unconscious in a nylon bag by a refuse collector in a building near his home in Castle Peak Road, Cheung Sha Wan. He was taken to Caritas Medical Centre but died before arriving.
A bruise was found on his neck and his plastic sword was with him in the bag.
According to Chi-fung's friend, who lives nearby, the pair were playing with toy swords in a playground near Block 7 of Un Chau Street Estate on Saturday afternoon when a 'middle-aged man' came up and told Chi-fung that he had a magic sword.
He asked Chi-fung to follow him to his home in the estate and Chi-fung's friend to wait in the playground.
The other boy went home instead. Chi-fung was not seen again until his body was found. Police are looking for a man aged about 30, standing 1.7 metres tall, of medium build and with short hair. Chi-fung lived with his decorator father. His mother and an elder brother live on the mainland.
His mother came to Hong Kong during the summer holidays on a two-way permit and often took Chi-fung to the playground and shopping.
'She loved Chi-fung a lot and bought him a pet dog before she returned to China,' a friend of the family said.
Chi-fung's neighbour said the boy was 'active' and 'polite'.
Police yesterday conducted a door-to-door appeal for witnesses and evidence.
