The police in Madrid have successfully apprehended the suspected killer of Ukrainian lawyer Andrii Portnov, who was shot dead on May 21, 2025, outside the school his daughters attended in Pozuelo de Alarcón, Madrid. The arrest occurred in Heinsberg, Germany, near the Dutch border, where the suspect had been located. This incident sparked significant public concern given the violent nature of the attack and the prominent status of the victim in the legal community.

Following the murder, agents from the Homicide Group of the Madrid Police force collaborated with the German Federal Criminal Police Office (BKA) to track down the suspect. Their coordinated efforts underline the transnational implications of this case, particularly as it involves a crime that has connections beyond Spain, reflecting the potential for international crime syndicates operating across borders. The investigation continues with searches being conducted in Heinsberg.

This arrest marks a crucial development in the ongoing investigation into Portnov's death. As a high-profile attorney, his murder raised questions about security for legal professionals in volatile contexts, especially given the tensions surrounding Ukraine. The case not only highlights the challenges faced by law enforcement in addressing organized crime but also the need for improved international cooperation to tackle such complex criminal activities effectively.
