COMIC fans rushing for the newest issues at a book fair at the Convention Centre yesterday shattered a four-metre glass door in a rugby scrum, injuring five teenagers. Fans, mainly students on summer holiday, had queued for more than an hour before the 11 am opening at the Wan Chai complex. The queue - about 6,000 people at its longest - stretched out of the Convention Centre, past the New World Harbour View Hotel, across Fleming Road, to the end of the shopping centre in Great Eagle Centre and doubling back to Fleming Road. Enthusiast Kwok Chi-chiu, said: ''It was really chaotic, the people were like tanks, pushing and shoving to get in.'' The 16-year-old said people surged forward into the closed ground floor entrance glass doors, one of which burst under the pressure. ''Everyone just raced into the ticket counters, not really caring that there was glass everywhere,'' he said. Another teenage fan said: ''People were pushing forward like mad when ticket sales started - and suddenly there came a hell of a bang. ''And when the security officers concentrated on restoring order at that corner, some people were jumping the queue,'' he said. A 14-year-old boy was taken to Tang Shiu Kin Hospital for minor wrist injuries. Four other youngsters were treated at the scene. The craze also swept the exhibition hall. Shoppers formed a 200-metre queue which doubled round half of the hall to buy comics of local publisher Jonesky - the most popular stall. A second-form student said: ''It's pleasure to read the new books as soon as possible. ''I spend just under $1,000 on comics every month. ''That's the largest chunk of my expenses, apart from meals,'' he added. More than 30,000 people visited the fair yesterday and the Trade Development Council hopes it can reap total sales of $40 million - doubling the figure from last year. More than 260,000 visitors are expected by Monday when the fair ends.
