More than £1.8m worth of cocaine was trafficked into Swansea in just five months by a criminal gang communicating over the secure EncroChat phone network.
It is estimated some 42kg of the Class A drug were transported to south Wales for onward supply to local dealers and users.
The operation was uncovered after Dutch and French law enforcement agencies were able to get access to the encrypted phone network, a network criminals had previously thought to be unbreakable.
