A Solidarity activist was arrested as thousands of Poles laid wreaths at a monument to victims of a 1956 uprising in the western city of Poznan. The uprising, in which 74 people were killed and 574 wounded, was the first workers’ revolt in Communist Poland. The only reminder of the uprising in Poznan is the monument--two 60-foot-high crosses inscribed “For Freedom, Law and Bread.” With scores of police watching and sometimes checking identity documents of those laying wreaths beneath the crosses, people applauded when Solidarity activist Janusz Palubicki was arrested as he laid his wreath. No reason was given for his arrest. Solidarity founder Lech Walesa was prevented from attending the ceremonies.
