A Moroccan police statement reported the arrests of the 6 aged between 15 and 17 after the incident in the kingdom's economic capital Casablanca.

In the footage posted on Sunday, six bare-chested teenagers are seen assaulting a weeping young woman and laughing as they touch her private parts.

The half-stripped victim is seen crying out in distress as no passenger intervenes to help her and the bus fails to come to a halt.

Public transport company M'Dina Bus said the incident happened on Friday.

The police statement said the 24-year-old woman suffers from a mental handicap, and that no complaint was filed by either the victim or the driver before the video was released.

The latest incident comes less than 2 weeks after footage of men hounding a young woman walking alone in the northern city of Tangier was shared widely on social media, sparking a heated debate in the North African country.
