She also said that an improvised explosive device (IED) was found in the detained suspects' apartments during a police raid, along with firearms and ammunition. A bomb also was found and disarmed in the apartment shared by the three suspects on the outskirts of St. Petersburg.

Victims' faces were ripped off when the the former sushi chef killed 14 by detonating a bomb on a crowded metro train in theRussian city on Monday.

"Orders have been given to return (the evacuated) residents, everything is safe up to the seventh floor", he continued, adding that police were still searching the building's eighth and ninth floors.

The investigative committee said the six Central Asian citizens were detained as part of a joint operation by investigators, the Federal Security Service, the Interior Ministry and the National Guard.

The impoverished, predominantly Muslim countries in Central Asia are seen as fertile ground for Islamic extremists, and thousands of their residents are believed to have joined the Islamic State of Iraq and Syria (ISIS).

St. Petersburg was already on high alert after an explosion between two subway stations Monday killed 14 people and injured dozens others.

People stand around candles showing the time of the subway bombing as they gather in memory of victims of the tragic event, on Marsovo Polye in St. Petersburg, Russia, Wednesday, April 5, 2017. He has named Daesh as one of the reasons behind Russia's military campaign in Syria in support of Syrian President Bashar Assad.

The detainees are suspected of being active since November 2015 in recruiting other Central Asian immigrants for "terrorist activity", and for ISIS and another banned Islamist movement, Fateh al-Sham, previously known as the Nusra Front.

Investigators said there was no evidence linking the six men to Monday's bombing. It's unclear if the raid Thursday was linked to the attack earlier in the week. Her husband, Alexander Kaminskiy thanked everyone saying "The country and the entire world share our pain".

Russian news agencies reported that law enforcement agencies had arrested three people, but did not say if they were men or women.
