Queensland Police could be using Stingray phone interceptors to unlawfully download the contents of your smart phone.

It is a common practice with American police to pull up beside a car at the lights and download your phone without you knowing it.

A motorist reported that she was traveling on the Mulligan Highway near Cooktown when she was intercepted by a police car which had been attending the Aurukun riots.(Aboriginal community)

The motorist tried to download messages when she got to her destination not long after the police intercept.  She said her phone had been working perfectly before she was stopped.

“The phone went beserk, throwing up messages, the screen was jumping all over the place so I tried to turn it off, but couldn’t do that either,” she told Cairnsnews.

“After playing with the phone I managed to turn it off for about an hour then when I turned it back on it did the same thing. I let it go flat and charged it overnight and today it seems to be OK.”

The motorist said a passenger in the car had the same problem and had to leave it switched off all night while on the charger.  She said this phone now seemed to work properly after receiving a call from the passenger complaining about the same problem.

A technician said the phones had displayed symptoms of being externally downloaded.
