Czechoslovak police detained 15 human rights activists, including former Foreign Minister Jiri Hajek and an American member of the International Helsinki Federation, dissidents said. Olga Havlova, wife of dissident playwright Vaclav Havel, said they were detained when they arrived for a meeting at a restaurant in Prague, the capital, with a delegation from the Vienna-based federation, which monitors human rights violations. Jeri Laber, a member of U.S. Helsinki Watch, was also detained after taking photographs of police but was released shortly afterward, dissident Anna Sabatova said. The others were freed by nightfall, an emigre source said.
