From IB Times:
On Thursday, Tehran police chief Brig. Gen. Hossien Sajedinia has warned that all women sporting a tan will be arrested and imprisoned because this violates the "spirit of Islamic law." Thus, any woman that looked like a "walking mannequin" will be punished.
He said that the Iranian public expects the police to act firmly and swiftly to any social misbehavior caused by women, and men, particularly those who defy the Islamic values. He cited some areas in northern Tehran where suntanned women and young girls look like walking mannequins.
"We are not going to tolerate this situation and will first warn those found in this manner and then arrest and imprison them," Sajedinia said.
