Has every single country that has a lot of tourists, the pickpocket is a reality. Make sure you pay to your wallet and backpack. Especially if you are near a famous tourist attraction, shopping malls, public transportations, and markets. These guys sometimes act alone sometimes they act in a group. One distracts you and other one pick your stuff. Always keep your belongings safe near your body. Avoid using back pockets and pay really close attention to your backpack.
