WARSAW, Poland (AP) — Polish police forcibly removed dozens of people staging an anti-government demonstration in Warsaw, including a hero of the anti-communist Solidarity movement.

The demonstrators gathered in central Warsaw on Saturday evening and attempted to block the movement of a group led by Jaroslaw Kaczynski, leader of the ruling conservative Law and Justice party. The group was commemorating the 2010 plane crash that killed Kaczynski's twin brother President Lech Kaczynski and 95 others in front of the presidential place.

Some of the protesters chained themselves together on the street to protest what they believe is the use by Kaczynski of the crash for political purposes.

Police used bolt cutters to cut the chains and hauled off dozens of protesters, including Wladyslaw Frasyniuk, a leading figure of the anti-communist opposition in the 1980s.
