In Simferopol (centre of the Republic of the Crimea, Ukraine), the local security service eliminated a number of drug dealers' dens which sold so-called "heavy drugs". This was done during a large-scale operation to stop illegal drug-trafficking. The press group of the Crimean security service informed RIA Novosti of this Saturday. An enterprising owner of a flat in the Crimean capital offered to his clients heroin ready for use, synthesised opium and syringes. His "service centre" was visited by several hundred people a day. At the time of the special operation, there were 13 people in the flat, but its owner managed to flee. Another drug dealers' den also offered opium ready for use. It was traded through a small window, and those who were in a hurry were "serviced" in the yard or at a deserted bathhouse. Criminal cases have been opened.
