A 42-year-old guy named Mack Yearwood from Stuart, Florida has been wanted since last October for violating his probation. And the cops posted a fake “wanted” poster for him on their Facebook page.

Well, he saw their post. And apparently he liked it so much that he downloaded it and made it his OWN profile photo in March.

The cops suspected him on another battery charge last week, so they started researching him to see if they could track him down, and they turned to Facebook.

And thanks to his profile photo, they knew which profile was DEFINITELY his . . . and they used the info there to figure out where he was staying.

He was arrested on Tuesday. (Fox News)
