A lawyer informed media agencies that two former cyber security experts at Russia’s FSB intelligence agency and one from a software company were charged with treason.
Dmitry Dokuchayev and Sergei Mikhailov – the ex-FSB men – and Ruslan Stoyanov, a Kaspersky executive, have been jointly accused for having worked for the interests of the United States, reports ABC News.
There are suggestions that the arrests can be associated with the recent claims of Russian involvement in the US elections.
But Kremlin has denounced such allegations.
Ivan Pavlov, who represents one of the men, provided the names of the arrested persons.
The local media reported that Mr Mikhailov, the former deputy head of FSB’s cyber-security department, was dramatically dragged out of a meeting with a bag over his head.
Sarah Rainsford, a BBC correspondent in Moscow, said that mystery still reigns over what led to the arrests with claims that they were as a result of the Obama claims that Russia hacked the US voting systems in two states.
But President Vladimir Putin, through his spokesperson Dmitry Peskov, said that the arrests cannot be associated with that and Russia has insisted it played no role in the hacking.
The other suggestion is that these men are linked to Shaltai Boltai (Humpty Dumpty) – a Russian hacking group. The group is attributed for having exposed dirt done by Russian political figures and then made it public.
