Australian police were confused as to where a bag of methamphetamine on the floor of a petrol station came from.

On Monday, as they checked the CCTV to find the culprit, the Western Australia Police force got a surprise.

A crow had fished the drugs out of a nearby bin and put the bag of illicit substance on the floor.

The bird then fled the scene, leaving the drugs at the petrol station.

Police seized the drugs and are trying to find out who binned them.
