The case risks rekindling tensions between Poland and Russia, exacerbated by drone crashes on Polish territory last autumn
According to Polish officials, Skrepetsky was shot three times on Monday morning by an unidentified gunman armed with a handgun. When the artist fell to the ground, he was approached by the assailant, who fired two more shots at close range.
The Polish government says it had offered Skrepetsky protection, which he declined.
Two Belarusian citizens were arrested in conjunction with the artist’s death, but they have since been released, according to Polish officials. An investigation by Polish services is ongoing.
