This is why they warn you to always be aware of your surroundings. 

The 'Pokemon Go' hype train has definitely died down, but the hardcore fans are still out there trying to catch them all. For instance, this guy known as Rickey Bot. He actually streams his 'Pokemon Go' experience. Basically, you're watching him play the game live.

The other day he was walking around his town, trying to catch a Seaking. When all of the sudden, someone beats him over the head and takes all of his stuff. It was all caught on camera and it was a pretty scary situation. He will probably avoid that part of town when he plays again, after he gets a new phone.
