Tens of thousands of people jammed the streets of Sham Shui Po yesterday in a mad scramble for heavily discounted electronic products on sale at a computer festival. The numbers prompted police to enforce crowd-control measures. By 9.30pm, at least 120,000 people had flocked to the festival at Fu Wa Street. The turnout was the highest in seven years, said the organiser, the Chamber of Hong Kong Computer Industry, which had to take the unusual step of appealing to people stay away until today or tomorrow. Police had to close one lane of Yen Chow Street. Some bus stops and an entrance to the MTR station were also closed temporarily. The organiser said more than 210,000 people had been to the annual festival over the past two days, and its turnover was about HK$65 million. Most visitors said they wanted to buy products such as monitors, laptops and storage devices, which were said to be discounted at least 30 per cent. However, some visitors complained that the large crowds made shopping so difficult that they left empty-handed. Last year, 380,000 people attended the festival and spent about HK$180 million.
