Here's how easily perps can swipe your cell phone on the Metro. Always watch your surroundings and don't sit near the door.

You always hear about it, but hopefully it's never happened to you... you're riding on the Metro, just minding your own business flipping through your news feed when you pull into a stop that isn't yours...while waiting for the doors to close, before you know it, someone's grabbed your cell and slipped right through the closing doors... with no way for you to chase after.

Here's how easy it is. Literally takes seconds and this unlucky victim never saw it coming. 

Good news: thief was caught and she got her phone back...
