A gunman opened fire on the Russia’s FSB’s main building in Moscow on Thursday evening in a shooting incident that left at least one FSB employee dead and five other people wounded.
Initial reports suggested three people had been killed but this was later revised down.
It was not immediately clear what the shooter’s motive was.
Security services on Friday searched the home of a man named by Russian media as the prime suspect in the rare shooting incident, neighbours told Reuters.
There has been no official confirmation of the identity of the gunman, who the FSB said it had killed. But some Russian media, citing unnamed sources, have named the suspect as Yevgeny Manyurov, a 39-year-old former private security guard.
Manyurov lives with his mother in a five-storey Soviet-era apartment block in the town of Podolsk in the Moscow Region. His neighbors, who described Manyurov as a quiet gun enthusiast, told Reuters on Friday that the FSB had raided the family home in the early hours of Friday morning.
There was no immediate comment from the FSB.
Unverified videos shared on social media showed several people resembling police officers holding assault rifles running along a nearby street.
One witness told Reuters he had seen the lifeless body of what he thought was a police officer lying in the street.
“The shooting began around 17:40,” one witness told Reuters. “I saw a member of the traffic police running down the road, hiding behind vehicles.”
Five ambulances were seen leaving the cordoned-off area.
