Heading to a music festival with some ecstasy in a sunscreen bottle or chewing gum packet?

Police are warning their dogs will sniff you out.

Acting Inspector Don Brown said the dogs would target tomorrow's Parklife festival and were aware people had developed several concealment methods to avoid being detected.

“Police are aware of these techniques, and we will be on the look-out for all drugs, no matter how well they are hidden," he said.

“Our police dogs are skilled in the areas of tracking, searching, protecting life and property and their sense of smell is fifty times greater than that of humans."
