Riyadh police have arrested 10 people — nine Saudis and a foreigner — after a video circulated online showed gunshots being fired in a car showroom and a Mercedes being set alight.
Two people injured in the incident were taken to hospital.
The Saudi Ministry of the Interior said that the violence in the capital was linked to a dispute between drug dealers.
Those arrested have been referred for prosecution, the Saudi Press Agency reported.
Other suspects have been identified and more arrests are taking place.
