North Korea is denying media reports that it was hosting an illegal casino in its embassy in Moscow.

Earlier this month, Russia media reported on a series of raids on 15 underground gambling dens in the Moscow region. Russian investigators believe the illegal operation had been around since May 2016, generating profits of hundreds of millions of rubles each month.

These illegal operations were reportedly connected to licensed sports betting operator Panorama, which operates the GreenBet, UnionBet and Winline brands. Over 100 individuals were arrested, including Anton Bazhanov, a reputed high-ranking member of the local “criminal community.” Kommersant reported that Bazhanov offered to put up RUB10m (US$153k) bail but was ordered held in custody for two months while his case progresses.

On Wednesday, the Tass news agency quoted a law enforcement source saying that one of the underground casinos was located “on the premises of the North Korean embassy” and that it catered to a VIP clientele of diplomats and lawyers.
