The anti-harassment measure, which was approved on Monday by the Shura Council advisory body, introduces a jail sentence of up to five years and a 300,000 riyals (£60,345) fine.
Saudi Arabia's decision to crack down on sexual harassment comes as the kingdom has been working to reform its oppressive policies toward women.
