WARSAW, Poland -- A man disturbed monthly observances in memory of Poland's late President Lech Kaczynski and 95 others who were killed in a 2010 plane crash, climbing the memorial to the victims and shouting at Poland's top politician Friday.
The man climbed the stairs-shaped monument in Warsaw as ruling party leader Jaroslaw Kaczynski, the late president's twin brother, and other ceremony participants were approaching to lay flowers.
He held a banner with anti-Kaczynski text and shouted "You are cheating the people" and other exclamations in the Law and Justice party leader's direction.
Two police officers brought the man down and took him into custody. Warsaw police spokesman Sylwester Marczak said he was brought to a police station for questioning on allegations of disturbing public order.
If charged and convicted, he could be fined or ordered to perform community service.
Jaroslaw Kaczynski has held monthly observances for his brother and the other people who died ever since the April 10, 2010, crash in Russia. He stopped organizing them last year as memorial marches, events that consolidated support for the right-wing Law and Justice party but also drew criticism.
Kaczynski and his party allege Russia had a role in the airplane crash. Aviation experts said it was caused by human error while the plane landed in poor visibility at a rudimentary airport in Smolensk, Russia.
