A surveillance photo shows Dzhalilov walking through the metro station, carrying what was later found to be an incendiary device inside his backpack.
He detonated the device around 2:40 p.m. inside a train car that was moving between the Tekhnologichesky Institut and Sennaya Ploshchad metro stations. Fourteen people are dead as a result of detonation, with 49 others injured.
A second, more powerful device with Djalilov’s DNA on it was found and defused at Ploshchad Vosstaniya station. It contained a kilo of TNT and ball bearings, and was hidden inside a fire extinguisher that was placed in a bag on the platform.
A motive has yet to be established but there is rising speculation that the attack intended to deliver a message as the suspect was known to be closely linked with radical Islamist groups. President Vladimir Putin was in St. Petersburg on the day of the explosion.
