A Saudi prince was arrested Thursday on King Salman's order, a state-run broadcaster reported, as outrage grew on social media over videos appearing to show him abusing members of the public. Salman issued a warrant for "the immediate arrest and imprisonment" of Prince Saud, a descendent of Saudi Arabia's founder, along with a group of men who appeared in the videos uploaded to YouTube, Al-Ikhbariya television reported. A video circulating on social media showed police escorting the young prince - one of the thousands of members of the royal family - out of a house in handcuffs.
