Police are on high alert as a foldable gun which looks like an iPhone is set to go on sale within weeks.The handgun - which has already had12,000 pre-orders - is disguised as a smartphone but can unfold into a deadly weapon at the press of a button. European police are being warned to look out for the guns which are expected to be illegally imported into the continent and appear on streets soon.The 9mm double-barrelled pistol has been made by American firm Ideal Conceal and costs £325 ($395) - well below the cost of the latest Apple iPhone, the Times reported.The company behind the legal gun said: “In today’s day and age, carrying a concealed pistol has become a necessity. But what if you didn’t have to conceal?”“Smartphones are everywhere, so your new pistol will easily blend in with today’s environment. In its locked position it will be virtually undetectable because it hides in plain sight.”Local newspaper Dernière Heure said an alert sent to police in Belgium police read: “To the eye, nothing can distinguish it from a mobile telephone. “Most people possess a smartphone, meaning that it can pass completely overlooked.” Head of the company Ideal Conceal, Kirk Kjellberg, said he got the idea after a child saw his own gun in a restaurant and got scared.“There are some people that would take serious issue in the workplace or somewhere else to see a gun on you, and I think it gives people the opportunity to avoid that conversation,” he said last year.Source: Evening Standard
