MOSCOW -- Several Russian opposition activists were temporarily detained in front of the Russian parliament's upper chamber as Prosecutor-General Yury Chaika was sworn in for another five-year term.
The activists held placards saying "Support For Chaika Is Support For The Tsapoks," a reference to the notorious Tsapok Gang that was blamed for extortion as well as numerous killings and robberies in Russia's Krasnodar Krai.
Russian opposition leader Aleksei Navalny has accused Chaika of having links to the infamous gang that made headlines in 2010 by killing 12 people in one evening.
Police released the detained activists hours later.
In December, Navalny's Anticorruption Foundation accused Chaika and his two sons of corruption and illegally amassing large sums of money.
Chaika -- who has been in his post since 2006 -- said after being reapproved for the post on June 15 that Hermitage Capital co-founder William Browder, an American-born British citizen, is one of those who is behind the "lies" about him and his family.
Browder has accused Russian tax officials of carrying out large-scale fraud that was uncovered by his lawyer, Sergei Magnitsky, who died in prison in 2009 after failing to receive proper medical care.
Browder was convicted in absentia in 2013 of tax evasion by a Moscow court and sentenced to nine years in prison.
