Panic was sparked at a Perth service station when staff wrongly feared a cashier had been attacked with a chemical.

An ambulance was called to the service station in Malaga, only to be stood down moments later when staff realised it was water that had been thrown.

The unhappy customer was taken into custody by police to be questioned over the alleged assault on Monday afternoon.
