Punishment: Charges dropped.
On November 15, 2010, two members of politically-motivated street art collective VOINA were arrested in a house raid in Moscow. They were taken away in a white van with plastic bags over their heads, with police telling their friends they were taking them "to the woods."
VOINA are most well-known for drawing a giant penis on the elevating St. Petersburg bridge. However, they really ticked police off after overturning a bunch of cop cars—at least one with an officer inside—as part of a public performance piece called "Palace Revolution."
After four months in prison, the two VOINA members were freed when BANKSY paid 300,000 roubles each for their release. Presumably because of the amount of international attention the case received, the charges were later dropped.
