Police in Xiamen, Fujian province, have closed 45 of the city's Internet cafes because they provided pornography, electronic games or were unlicensed. In March last year, the city government invited applications for Internet cafes, the Legal Daily said at the weekend. Many became electronic games rooms that attracted children and sparked a strong reaction from parents and teachers, who dubbed them 'electronic heroin'. As a result, police have passed a new regulation banning such cafes from being set up within 200 metres of a school. A survey of the cafes' users found 45 per cent were high-school students and 35 per cent were young people who had left school. About 55 per cent used the Web for chatting, 30 per cent to read newspapers and other material and 10 per cent to send and receive e-mail and obtain information on stocks and shares. The city's Public Security Bureau said it must step up its role as 'Internet policeman'.
