Shipilov was detained at a railway station outside Moscow on 11 September.
The same day newspaper Novosti Kuzbassa published his interview with Artyom Loskutov, who sought to organise a march for the 'federalisation' of Siberia.
The march last month was banned amid claims of extremism.

Police say he was detained over an unrelated incident.
In 2012 he was sentenced to 11 months corrective labour for a public insult of Aman Tuleyev, governor of Kemerovo.
He was reported to have fled from Kemerovo. His sentence was replaced with detention in a penal colony for three months, and police say this was the reason for his detention.
Archeologists discovered a new stone bracelet, two sharp pins, a marble ring and fox tooth pendants.
