The FSB reported that it had thwarted a terrorist attack targeting a senior police officer.
Police discovered the scooter parked near the entrance to the business centre, with a powerful bomb hidden in its trunk disguised as a household charging station.
“The SBU planned to remotely detonate the device during the target’s visit to the business centre, identifying him through organised video surveillance," the statement said. "This could have led to a large number of civilian casualties.”
Bomb disposal experts recovered the device at the scene.
It reportedly contained around 1.5 kilograms of plastic explosives, along with shrapnel such as nuts and bolts.
The device was reportedly controlled via a smart home Wi-Fi relay system and a 4G modem.
