ST. PETERSBURG, January 29 (RIA Novosti) – Vandals spray-painted the word “pedophile” on the wall of a museum dedicated to famous writer Vladimir Nabokov in St. Petersburg, Fontanka.ru city news website reported on Tuesday.

The wall was spray-painted by the same group of self-styled “St. Petersburg Cossacks” who broke the museum’s window on January 9 and have been sending ominous letters to the museum, accusing the writer of propagating pedophilia and threatening “God’s wrath,” Fontanka.ru said.

The Nabokov Museum is located in the mansion on Bolshaya Morskaya street where the celebrated writer and poet was born in 1899 and lived until November 1917.

Nabokov is best known for “Lolita” (1995), a story with pedophilic connotations, but was never accused of child abuse himself.

A one-man show based on “Lolita” was canceled in St. Petersburg by its author in October 2012, after he received threatening letters from the anonymous “Cossacks.” However, the performance took place in December and January, and its organizer was beaten by three unidentified attackers.
