The culprit resisted arrest, opening gunfire at police officers, wounding three of them as well as a bystander who happened to be at the crime scene as the shootout unfolded.
The attacker was killed as law enforcers returned fire. A person, who is referred to as the attacker's accomplice, was also shot, reportedly by the culprit himself.
Several other suspects have been detained, according to a local police report which did not specify their number, according to Hromadske TV.
One of the wounded police officers is now in critical condition, according to the report.

Dumskaya, a local news outlet, later identified the shooter as an Odesa resident Valentyn Doroshenko, who “referred to himself as a member of Stalin’s Party”. In 2010, the man even ran for the city mayor and, in a controversial campaign move called the then-Mayor Eduard Hurvits on a duel.
The individual is reported to have been in the focus of law enforcers over his involvement in a riot outside the local police department HQ in the fall of 2013 when a group of perpetrators attempted to forcefully release from custody Ihor Markov, the detained leader of a pro-Russian Rodina Party.
