The crime was carefully prepared, the attacker studied the victim's movement pattern, mapped the route and prepared the escape, says the Ukrainian Interior Minister Ihor Klymenko according to Kyiv Independent.
Also, the police chief Ivan Vyhivskyj says that the crime was not random, and that there is a "Russian trail" behind it, according to the newspaper, without going into details.
One person has been arrested, announced President Volodymyr Zelenskyj during the night to Monday.
"The necessary investigative measures are underway", the president writes on social media, and thanks at the same time for the "quick and coordinated work" being done.
Zelenskyj also states that the suspect has been interrogated.
Parubiy was the speaker of the Ukrainian parliament, the Verkhovna Rada, between 2016 and 2019. Before that, he served as the head of Ukraine's National Security Council.
He also played a prominent role in the so-called Euromaidan protests in Ukraine in 2014, writes The Kyiv Independent. The protest movement, which advocated for a rapprochement with the EU, brought down the pro-Russian then-president Viktor Yanukovych.
He was 54 years old.
