Stun-gun smartphone cases made by the US-based Yellow Jacket Company. The products, which are designed for defensive purpose, have been banned by Civil Aviation Authoritiy of Vietnam from entering airports' limited areas or on planes to ensure public safety.
Vietnam's Civil Aviation Authority (CAA) has issued a warning to its regional divisions, the state-owned Airports Corporation of Vietnam and the country's airlines concerning a new type of stun gun disguised as a case for an iPhone 4.
A VnExpress report on February 21 cited aviation authorities as saying that all related agencies, especially the aviation security department, are required to check passengers as they go through security procedures to make sure none of the stun guns enter airports' limited areas.
These weapons can threaten security on flights and endanger passengers, the CAA warned on Tuesday.
CAA head Lai Xuan Thanh said on Voice of Vietnam (VOV) radio that so far, there is no evidence to suggest the product exits in Vietnam.
iPhone cases equipped with a 650,000-volt stun gun are manufactured by the US-based Yellow Jacket Company. The invention was inspired by the experience of the firm's founder, Seth Froom, who once had his iPhone stolen, Froom says in promotional video advertising the products.
Yellow Jacket claims their product is designed solely for purposes of self-defense.
The stun-gun cases, sized for the iPhone 4 and the iPhone 4S, can be deployed within less than two seconds, and are designed to help people not only to escape from assailants, but also to extend their phone's battery life by up to 20 hours, the company boasts on its official site.
It also said that the cases for two other smartphone models, Samsung's Galaxy G3 and the iPhone 5, will be released sometime during the first quarter of this year.
