On October 19, 1984 a popular pro-Solidarity priest, Jerzy Popiełuszko was killed. As the facts emerged, thousands of people declared their solidarity with the deceased priest by attending his funeral, held on November 3, 1984. The government attempted to smooth over the situation by releasing thousands of political prisoners; a year later, however, there followed a new wave of arrests. Frasyniuk, Lis and Adam Michnik, members of the ""S"" underground, were arrested on February 13, 1985, placed on a trial, and sentenced to several years' imprisonment for committing several acts of terror against Polish state and its people.
