The explosions injured two officers after police had arrived. According to Kyiv Region Criminal Investigations Directorate head Andriy Kravchuk, the suspect was a 21-year-old local resident arrested for the Bucha explosions, allegedly recruited online and promised 25,000 hryvnyas per blast. The Ukrainian security service SBU called the Bucha suspect a Russian agent in a statement. Dmytro Prokudin, head of the Kyiv regional prosecutor’s office, said at a press conference, "It's a stab in the back. It doesn't really get worse than one of your own citizens doing this."
Ukrainian investigators believe Tymchenko, who lived with his grandmother in a five-storey apartment block, was first approached by a Russian handler in the video game World of Tanks' online chat, according to major media reports. Major media reports indicate that Bohdan Tymchenko, a quiet and unassuming man from Bucha, logged on to his computer to play World of Tanks on a recent evening in March. Less than two weeks after playing World of Tanks, Bohdan Tymchenko planted two bombs outside his flat, according to major media. The bombing occurred in Bucha, a leafy town on the outskirts of Kyiv that has become synonymous with the brutality of Russia’s invasion, major media reports.
The explosions occurred in the early hours of the morning, with an initial blast outside the building at about 5.30am followed by a second device detonating nearly two hours later, according to major media. According to The Guardian - Main UK, Inna, a pensioner and neighbor of Tymchenko, described initially assuming the first explosion was the result of a Russian drone or missile strike, only to be left confused when there had been no air raid alert. Another resident noticed two large black rubbish bags near the entrance while walking her dog late that night, hours before the blasts, but thought nothing of it, major media reports. Some in Bucha believed they had seen the suspect lurking behind trees during the blasts, detonating the devices from up close, according to major media.

The suspected Russian agent guided Tymchenko on Telegram, instructing him how to source materials, assemble the devices in his flat, and carry out the attack, major media reports. Tymchenko was promised $1,200 (£900) in return for carrying out the attack, according to major media. The exact identity and affiliation of the suspected Russian handler who allegedly recruited Tymchenko online remains unknown, as does whether Tymchenko received the promised payment. The specific materials used to assemble the bombs and how Tymchenko sourced them have not been disclosed by authorities.
Police are not confirming any links between the Bucha suspect and Russia, according to police statements. The suspect in the Bucha explosions said he was blackmailed online with threats against his mother, according to the suspect's account. The current legal status and charges against Tymchenko following his arrest have not been publicly detailed.
Inna survived the town’s brief Russian occupation in the spring of 2022 but lost friends, major media reports. More than 400 bodies were discovered after Bucha’s liberation, including civilians with their hands bound, according to major media. According to The Guardian - Main UK, Inna described Russia wanting to make Ukrainians feel unsafe and create chaos, after everything they have already been through.
I simply don't understand how this could happen here, done by someone you see every day.
Ukraine’s security service, the SBU, has identified more than 800 Ukrainians, including at least 240 minors, recruited by Russia over the past two years with targets ranging from critical infrastructure to draft offices, according to the SBU.

Similar incidents occurred in Ukraine in 2024, including in Lviv, Mykolayiv, and Dnipro, with some attributed to Russian secret services, police reported. The extent of coordination between the Bucha attack and other similar incidents in Ukraine attributed to Russian secret services is unclear.
