Thousands of fans forced their way into the Bata Stadium complex for Saturday's opening match of the African Cup of Nations, prompting police to use tear gas, AP reported. Police tried to check fans' tickets one-by-one at the main gate to the complex ahead of Equatorial Guinea's match against Libya. But several times the crush proved too much and the gates were opened to allow scores of supporters through without being checked. On at least one occasion, tear gas was used on the crowd. The gate opens onto a road leading to the stadium proper. In theory, fans will still need a ticket to get inside.
