Polish authorities said that Russia had detained four soldiers on suspicion of looting credit cards from the body of Andrzej Przewoznik, a historian and top Polish official. Przewoznik perished with 95 other people, including Poland's president Lech Kaczynski, when their plane went down in thick fog near Smolensk airport in western Russia.

According to Warsaw, Przewoznik's card was used to withdraw money from a cashpoint within hours of the catastrophe. Further withdrawals were made from four Smolensk cash machines over the next two days. Przewoznik's widow raised the alarm when she discovered around 6,000 zloty (€1,400) had vanished from her dead husband's bank account.
