A stash of drugs was found at a St. Petersburg apartment being rented by a police lieutenant colonel, the local branch of the Federal Drug Control Service said in a statement Tuesday.
More than 36 kilograms of heroin, about half a kilogram of 3-Methylfentanyl and some 80 grams of methadone were discovered in the apartment, the statement said.
Authorities did not release the officers's name, but said he had been working with two other individuals who were detained last week. The lieutenant colonel was detained Friday as part of a yearlong investigation to identify all the members of the organized group, the statement said.
Investigators are now looking into how the drugs were shipped to St. Petersburg.
