DAKAR, Senegal (AP) -- An Associated Press reporter saw police tussle with international pop star Youssou Ndour, who was pushed back by police when he tried to enter a police station where a leading opposition figure is being detained.

Ndour had come on Saturday to the Criminal Investigation Division as part of a large crowd of opposition supporters who wanted to show their solidarity with Alioune Tine, a well-known human rights activist who is being questioned by police.

Tine was the organizer of a demonstration Friday that turned violent following the decision of Senegal's constitutional court to allow the country's leader to run for a third term. The legal body approved President Abdoulaye Wade's third term bid, even though critics say the constitution allows a maximum of two.
