When you're travelling through 195 countries, you're bound to get into some sticky situations. And this was definitely one of them.
Alexander Hemingway is travelling around the world as part of the Global Degree project and his trip recently took him to Argentina.
While on a bike tour through a rough neighbourhood of Buenos Aires, Alexander had a run-in with a pretty scary run-in with an armed robber on a motorbike.
In this intense video filmed from a GoPro in Alexander's helmet, we see a guy on a motorbike cut across him before pulling out a gun. He yells at him in Spanish to give him his backpack but, at the time, Alexander didn't understand what he wanted so he just left his bike and took off on foot, escaping unharmed.
The video footage was given to the police and the robber was arrested later that same day.
