Customs officers in Australia are warning of the danger of taser stun guns designed as phones.
Border staff say they have been discovering the devices coming into the country over the last 12 months – detecting 88 of them in 2012.
But they have been forced to admit that due to reporting procedures the real figure could be much higher.
A spokeswoman told the Sydney Morning Herald: “Not all were modelled on the iPhone or as phone cases – other brands have been detected.”
“The devices are more commonly disguised as torches – like Maglites.
”They are easily detected with X-ray technology as their image does not accord with a normal phone or case.”
A total of 2,600 stun devices, which are banned in Australia – were uncovered last year hidden in nearly 1,200 shipments.
Most, 58%, were detected through international mail and 37% by officers at the airport.
It is thought that the majority come from Hong Kong, China, the US and Singapore.
There are also concerns about a new iPad stun gun case that has recently gone on sale in the US.
It is legally sold in parts of the US and manufacturer Yellow Jacket this month distributed the first 3,000 of its iPhone stun gun case that retails for $139 US dollars (£92).
The concept was developed after one of the company’s founders was attacked in his home by an armed intruder.
The company plans to make cases for other popular smart phone brands that will be available later this year.
