"Bochkarev arrived at Moscow’s Sheremetyevo on a flight from Oslo. He was greeted by his son and colleagues," a press release by the Federation Council, the upper house of Russia’s parliament, read.
He was detained at an Oslo airport in September, after taking part in an IT conference in Norway’s parliament, on suspicion of gathering data illegally. Norwegian national security agency on Friday withdrew an appeal against his release, ordered by a local court earlier this week.
He thanked Russian diplomats in Norway, the Russian parliament and Federation Council Speaker Valentina Matvienko for their support. The Russian Foreign Ministry said it expected an apology from Norway, while Matvienko called the arrest a provocation.
