Russia's Federal Penal Service (FSIN) confirmed that Oleg Navalny had been put in Moscow's Butyrka detention center after he and his brother opposition activist Alexei Navalny were convicted on Tuesday of large-scale fraud and money laundering.
"Yes, he was taken to Butyrka," an FSIN spokesman told Interfax.
Butyrka's chief told the agency that Oleg Navalny had been brought to the jail before lunch and put in quarantine in compliance with the rules.
"Our quarantine conditions meet international standards. Navalny will have a medical examination, being seen by a psychologist among others, and then the commission will decide in what cell he will be kept," Sergei Telyatnikov said.
Telyatnikov said no complaints had come from Navalny and that "he has no health complaints."
Oleg Navalny was sentenced to three and a half years' imprisonment. Alexei Navalny received a suspended prison term of the same duration with a probation period of three years. The brothers are accused of swindling the Yves Rocher company of large amounts of money and laundering the cash.
