Tadeusz Jedynak, a leader of Poland’s banned Solidarity union who was captured this week, rejected an offer by authorites to free him if he would publicly recant his views, according to his wife, Maria. She said police drove her from her home at Zory to the Warsaw prison where her husband is being held and that she was “told to. . . persuade him to appear before radio and television microphones and have him ask the other (Solidarity leadership) members to come out of hiding in return for clemency for him.” She said Jedynak’s refusal means he could be charged under treason laws.
