The showing of a two-minute hardcore porno clip on a massive advertising screen caused a traffic jam in downtown Moscow as motorists "unable to believe their eyes" stopped their vehicles.
Moscow authorities pledged on Friday an inquiry into the incident, which took place on the Russian capital's central Garden Ring road late on Thursday
"We have received an inquiry and will look into it," a member of Moscow's advertising committee said. He refused to comment further. Other city officials also refused to comment.
The advertising firm that owns the billboard, 3Stars, said hackers were to blame for the "attack against our company."
There are no reports of any accidents caused by the screening of the clip.
