Copenhagen Police have arrested 12 people in connection with four separate cases of weapons possession.
The arrests are in connection with the killing of three young men in Frederiksberg in November – a crime that police have called an assassination.
Police said their investigation revealed that at least four weapons have been obtained by members of the group, allegedly to use to avenge the killing of their three friends. Three fully loaded pistols and a hunting rifle were seized.
The 12 were arrested during 19 raids in Greater Copenhagen, Zealand and Jutland and on Funen.
The suspects have been identified as both suppliers and buyers of the weapons, along with those they believed actively participated in the planning to procure the weapons.
Police said that all the suspects are men “with a different ethnic background than Danish”. They are between 16 and 30 years old.
