MOSCOW, February 13. /TASS/. The Moscow drug police stopped a major channel for supplies of Afghani heroin from Central Asia to Russia. The police detained 23 criminals and confiscated over 40 kilograms of heroin, the Russian drug control authority, FSKN, said on Friday.

"The police confiscated over 40 kilograms of heroin, which could be used for over 800,000 doses, and which could bring over one billion rubles (about $15 million) to the criminal group," FSKN said.

Specialists say the quality proves the drug originated from Afghanistan. A detainee organized a drug network in Moscow and a net of couriers in Tajikistan.

The police began following the criminal group in late 2014. In a park in Moscow, the police detained a couple as they were taking heroin from a hiding place.
