An enormous television screen showing a pornographic film caused a midnight traffic jam along Moscow’s Garden Ring Road as stunned motorists slammed on the brakes to gawk at the writhing naked bodies.

The owner of the 9-by-6-meter advertising screen said hackers had broken into the screen’s computer system and turned on the porn. “They were either acting out of hooliganism or were from a rival company,” Viktor Laptev, commercial director of advertising firm Panno.ru, told RIA-Novosti.

Authorities said they are investigating the incident, which lasted about 20 minutes. “Within three minutes we found it out, and within 15 minutes the screen was shut off,” said the deputy head of Moscow’s advertising committee, Alexander Menchuk, Interfax reported.
