SEATTLE (Nexstar) - The Seattle Police Department says an officer has been placed on leave and a use of force investigation is underway after video surfaced on social media allegedly showing a member of SPD riding his bike over the head of a fallen demonstrator during protests in the city Wednesday night.

Protests broke out across the nation Wednesday after a Kentucky grand jury considering the March killing of Breonna Taylor in her home voted not to indict any of the three white officers with charges directly related to her death. One of the three officers was indicted on a charge related to endangering Taylor's neighbors.
