Ukrainian President Volodymyr Zelensky announced the arrest of a suspect linked to the assassination of former parliamentary speaker Andriy Parubiy, who was shot dead in Lviv on Saturday. The suspect was reported to have fired multiple shots in broad daylight before fleeing the scene, according to police reports. Zelensky expressed gratitude towards law enforcement for their accelerated investigation efforts, stating, "All the circumstances of this horrific murder must be uncovered," according to SCMP and Dawn.

Parubiy, 54, was a significant political figure and a leader during Ukraine’s Euromaidan protests between 2013-2014 that ousted pro-Russian President Viktor Yanukovych. Following the assassination, multiple Ukrainian officials indicated that the killing appeared to have been planned meticulously, with police chief Ivan Vyhivskyi stating that the suspect had spent significant time preparing for the attack. “He spent a long time preparing, watching, planning, and finally pulling the trigger,” Vyhivskyi noted, casting suspicions of Russian involvement, as reported by Reuters and ABC News.

The suspect was arrested in the Khmelnytskyi region following a manhunt initiated immediately after the shooting. Interior Minister Igor Klymenko disclosed that the crime had been carefully plotted, emphasizing that the timeline of Parubiy’s movements was dissected prior to the attack. “The schedule of the deceased's movements was studied, the route was laid, and an escape plan was thought out,” Klymenko reported, highlighting the professionalism behind the act, according to BBC and Newsweek.

While the investigation continues, officials have yet to establish concrete evidence linking the suspect to Russian authorities, although preliminary indications suggest a possible connection to organized operations. “We have information indicating the possible involvement of Russian Federation security services in organizing the murder,” regional SBU chief Vadym Onyshchenko stated, according to Reuters and TRT World.
