BEIJING — A crowd of 30,000 people, baking in the heat and waiting for up to two days, swarmed a ticketing center Friday as the final batch of Olympic tickets went on sale. Police shoved and kicked them and used metal barricades to prevent a stampede.
The Aug. 8-24 Beijing Games are the first Olympics expected to be sold out, and some fans spent the night on thin bamboo mats and newspapers for a chance to buy the 250,000 tickets that went on sale in different parts of the city.
At the main ticket office not far from the national stadium known as the Bird's Nest, tempers flared as police yanked more than half a dozen unruly fans from the crowd, kicking one who fell as he was being led away and dragging another by his hair.
