Red Bull is facing a fine in Russia for breaching local advertising rules, according to reports.

The Kommersant-Sibir newspaper said today that the Russian arm of the soft drinks company has been hit with legal action by the Federal Antimonopoly Service (FAS) for the Siberian region of Krasnoyarsk.

The paper cited regional FAS director Oleg Kharchenko as saying that Red Bull had been running a Mini Cooper with a model of a Red Bull can on it around the streets of Krasnoyarsk. The use of vehicles for advertising in the region is forbidden by law, however.

Should the FAS win the challenge, Red Bull Russia could face a fine of up to RUB500,000 (US$19,721), the paper said.

No-one was available for comment at Red Bull's head office in Austria when contacted by just-drinks today (13 September).
