City authorities vowed on Friday to "find and punish" the "hooligans" who put up posters in central Moscow depicting Prime Minister Vladimir Putin as a secret agent.
The placards, which appeared on billboards and at bus stops earlier this week, announce a non-existent movie starring former KGB officer Putin.
They feature "Putin" in a black suit with a pistol in his hand. The caption says "VV [Putin's patronymic is Vladimirovich] will cover up for you."
The website advertised on the site is promoted as a "secret state project," masked as an all-Russia on-line quest computer game.
In May, posters featuring Putin and President Dmitry Medvedev apparently promoting a new collection of clothes at one of Moscow's most expansive malls appeared in central Moscow. The mall's management denied any links to the images.
