South Wales Police are investigating a case of fly tipping in Wenvoe whereby much of the contents of the bags provide evidence of cannabis cultivation..
In a statement Police said "fly tipping in this area is getting more regular."
"The images show some very distinctive looking bags that have been used to dump, and we ask that if anyone has seen these type of bags being used or recognises any property they may have come from, to report it to us."
A spokesperson for the Vale of Glamorgan Councils Enforcement team said "We are aware of the incident and officers are investigating. Arrangements will be made to get the waste removed by our cleansing team."
