What is "zangbeto"

Zangbeto are the traditional voodoo guardians of the night in the Yoruba religion of Benin and Togo which are known as the "Nightwatchmen". Similar to Egunguns, they are highly revered and act as an unofficial police force patrolling the streets, watching over people and tracking down criminals and presenting them to the community to punish. Originally created to scare the enemy away, Zangbeto will wander around the streets to detect thieves and witches, and to provide law and order.
