A judge has said police would be failing in their public duty if they did not properly investigate the international criminal gangs responsible for running cannabis farms in Wales.
The judge spoke out as he sentenced an Albanian man caught working as a so-called gardener in Swansea Valley house which had been given over to the production of the drug.
Judge Geraint Walters said it "should not be beyond the wit of man" for detectives to find out who was higher up the chain of command and to go after them, but in the experience of the courts it seemed police regarded catching catching a low-level gardener as "case closed".
