This one sweet my belle, just last month a driver hit an old woman on the road and didn't wait, the old woman survived it though but she had internal bleeding, I wonder why people can be so inhuman, you hit someone and because you want to avoid the medical bills, you run away.. This is the first time I am reading that they follow the driver and catch him...
there is a saying that no one is useless, even tout/ thugs can be helful.
Omo... I've seen something similar where they helped an accident victim back during my secondary school days. I can't remember if they snagged the driver then or not. But, I've seen multiple cases of these guys being unexpectedly nice.
