Russia's Investigative Committee have released footage of Darya Trepova, a woman suspected of involvement in a St Petersburg cafe blast which killed prominent Russian military blogger Vladlen Tatarsky.
Well-known as a cheerleader for Russia's military invention in Ukraine, Tatarsky was killed on Sunday in what appeared to be the second assassination on Russian soil of a figure closely associated with the conflict.
Russian investigators said they had arrested 26-year-old Ms Trepova, whom they said was suspected of bringing the explosives into the St Petersburg cafe.
