The Russian Federal Security Service (FSB) announced that the suspect, Lyubomyr Korba, a 1960-born Russian citizen originally from Ukraine’s Ternopil region, was apprehended in Dubai and transferred to Moscow for questioning.

The FSB said the operation was conducted jointly with the Russian Ministry of Internal Affairs and in coordination with "partners in the UAE,” marking one of the most high-profile cross-border arrests since Russia intensified security efforts around senior defense officials. 

According to FSB, Korba arrived in Moscow in late December 2025 "under orders from Ukrainian intelligence services” to carry out the attack.

Russian investigators say Korba fired at least three rounds from a suppressed Makarov pistol inside a residential building in Moscow on 6 February 2026, injuring Alekseyev, who remains hospitalized. The Investigative Committee of Russia said forensic teams recovered the weapon and spent cartridges at the scene.

Authorities also identified two alleged accomplices: Viktor Vasin, born in 1959, who was arrested in Moscow, and Zinaida Serebrytskaya, born in 1971, who fled to Ukraine. Both face charges of attempted murder of a military officer and illegal possession of weapons.

Investigators say the search for the alleged planners is ongoing. "All operational measures to identify the organizers of this crime are continuing,” the Investigative Committee said, noting that Korba left Russia shortly after the shooting and attempted to evade capture abroad.

The case has drawn regional attention given the Kremlin’s claims of Ukrainian intelligence involvement, though Kyiv has not commented publicly on the accusations.
