The spokesman said the drugs were smuggled into Russia in one of the freight carriage's refrigerated goods compartments on a train bound for Orenburg from the Uzbek city of Kokand.
Once in Orenburg, he said, the freight wagon was amalgamated into another train en route to Chelyabinsk. Those involved in the smuggling operation then threw bags containing 110 packets of heroin out of the good's wagon.
Police officers arrested a Tajik national, who was due to collect the drugs, along with two Uzbek men, who threw the narcotics from the train.
The spokesman added that "the heroin was carefully packed in 110 packets, which had stamps with Arabic writing on them and pictures of a scorpion, lion and deer, which suggested that the drugs were of Afghan origin."
If found guilty the three suspects face up to 20 years in prison.
Most of the heroin and hashish coming into Russia is from Afghanistan and then trafficked through the former Soviet republics of Tajikistan and Uzbekistan. Most of the drugs are then sold in Russia's largest cities of Moscow and St. Petersburg.
