Three Vietnamese men were arrested after the owner of a CD shop was stabbed to death in Tuen Mun Town Plaza. Police said Lee Chi-ming, 32, was stabbed as he put up a struggle to protect $37,000 in takings. He was attacked on the upper ground floor of the plaza in Tuen Shing Street at about 10.30pm on Thursday while on the way to the car park. The victim was declared dead at Tuen Mun Hospital early yesterday. A black nylon bag with the $37,000 inside and a box containing VCDs were found at the scene. The three suspects, aged 17, 21 and 27, were arrested at the Pillar Point refugee centre.
