Authorities frequently use degrading punishments against youths in their local neighbourhood so as to embarrass and humiliate them.
Such punishments are often used for petty crimes such as alcohol consumption, disregarding nightly curfews, and disrespect towards security agents.

The 18-year-old, identified only by his first name Mostafa, was tied to a tree in the Iranian capitals district of Razi for four hours charged with being a trouble-maker.
