A court in Moscow has prolonged the pretrial detention of a Russian ultranationalist extradited last week from Cuba.
The presiding judge ruled on February 7 that Maksim Martsinkevich -- also known as "Tesak" (Machete) -- must remain in custody until April 10.
Martsinkevich, who was formally charged with extremism last week, has refused to answer investigators' questions.
Last year, Martsinkevich founded a homophobic group, Occupy Pedophilia, whose aim was to "cure" homosexuals through humiliation and torture.
Several videos of Martsinkevich and his followers humiliating and beating gays circulated on the Internet in 2013.
If found guilty, Martsinkevich faces up to five years in jail.
He was detained by Cuban law-enforcement agencies in Havana on January 17 for staying in the country without a valid visa for more than 30 days.
