Former world chess champion turned Kremlin critic Garry Kasparov has been on the receiving end of an unconventional prank launched by his political foes - one that draws its inspiration from the virtual world of Second Life.
Kasparov was attending a weekend meeting of a coalition of opposition groups which had assembled in Moscow to launch a symbolic alternative parliament. As he was addressing the gathering of more than 500 delegates, he was buzzed by a remote-controlled flying phallus.
The device - which appeared to be a modified twin-rotor toy helicopter - caused a sudden commotion with security guards springing to attention.
A video shot at the event shows the modified chopper briefly evading capture before a man later identified as a security guard leaps from the stage and swats the device with a well-aimed left hook.
According to the Moscow Times website, the prank was staged by "a couple of pro-Kremlin Young Russia activists" who had launched a "plastic phallus on propellers".
