Free money ignored in Manchester social experiment

They say nothing in life is free. So when £25 was seemingly abandoned in the middle of Manchester city centre it was met with suspicion.

Especially as it came with one vital stipulation - "for people in need only."

It was placed there by social media company "The Lad Bible" - not as an act of kindness or charity - but as a social experiment. So what happened?
