Police Rout Solidarity Protest

GDANSK, Poland —  Police broke up a pro-Solidarity demonstration and arrested 10 dissidents in Wroclaw today as the outlawed union’s founder Lech Walesa, marking the movement’s seventh anniversary, laid a wreath at a workers’ monument in this city.

Walesa sang the national anthem with a crowd of 1,500 at the monument in front of the Lenin Shipyard. Police were in the area, but they did nothing to stop the ceremony. The three 30-yard-high crosses were built in memory of more than 50 people killed by police during a 1970 revolt in the city on the Baltic coast.
