A biker intervenes in a laundry mugging and becomes a hero

In a laundromat in Armenia, Colombia, an American tourist couple is attacked by a knife-wielding robber. As the man flees, the woman bravely defends herself. A motorcyclist intervenes, removes his helmet and hits the assailant on the head. Passers-by join him in subduing the criminal, who is then dragged from the scene.
