A total of 24 European countries supported by EU institutions and agencies including Europol, have come together to target alarm and signal weapons of Turkish origin illegally trafficked into the EU via Bulgaria and other countries. To tackle the increase in weapons illegally transformed and traded, operation BOSPHORUS was setup and led by the Romanian Police (Politia Romana) within the framework of the European Multidisciplinary Platform Against Criminal Threats (EMPACT). Supported by Europol, authorities collected data and conducted intelligence analysis of the buyers and sellers of firearms earlier this year to enable series of investigations and activities on a national level.
Between 2 and 11 November the yearlong operation BOSPHORUS was concluded by joint action days. During the span of the action days, police officers from Albania, Greece, Portugal and Romania carried out 81 house searches.
These investigations led to the following arrests and seizures:
- 11 arrests;
- 191 firearms;
- 3 714 cartridges of ammunition;
- small quantities of drugs including cannabis and cocaine;
- unstamped cigarettes packs;
- 1 vehicle;
- 164 pieces of pyrotechnics;
- false ID documents.
Previous results: prior to the action days, all participating countries conducted various activities and investigations that led to the additional seizure of 1 585 firearms.
The action leader of the EMPACT Firearms activity from the Romanian Police coordinated the operation with the support of Bulgaria, Spain and Europol. The framework for the joint action weeks consisted of an operational upstream work performed by gathering intelligence, databases crosschecking and operational analysis of buyers in the EU of weapons from Bulgarian firearms dealers. Europol provided further support during the course of the action days with the exchange of information and real time communication among the participating countries.
In recent years, alarm and signal weapons have become extremely popular among criminals and feature in considerable figures in firearm trafficking and seizure cases. This is due to the fact that they can be easily converted into lethal weapons and are cheaper to procure.
Europol plays a key role in supporting Member States fight criminal networks involved in illegal weapons and explosives trafficking. As part of a wider strategy to identify the criminal networks supplying terrorist groups with firearms and ammunition, Europol experts work closely with counter terrorism experts on international investigations. Moreover, Europol specialists and analysts combine efforts to assist Member States in developing their own resources to monitor and tackle the dark web phenomenon.
