A man drove into a Seattle crowd protesting the death in police custody of George Floyd before shooting one of the demonstrators on Sunday.
The suspect was detained and the 27-year-old man who was shot in the arm was taken to hospital by firefighters, police said in a tweet. Officials did not name the shooter or the victim.
Police confirmed a gun was recovered and no other people were injured.
Video shared on Twitter by a bystander at the incident showed a man emerging from a vehicle that appeared to have struck a barricade at an intersection. The driver appeared to be carrying a gun in one hand as he ran into the crowd. The sound of what appeared to be gunshots could be heard on video of the incident from the scene.
One witness told that the victim had tried to stop the vehicle from driving into the crowd before the driver shot him.
