A King County Superior Court juvenile probation officer who says she was harassed by Seattle Police Department officers last month has been charged with misdemeanor assault.

Yvette Gaston, who described her encounter with police at an NAACP press conference on racial profiling two weeks ago, says she was grabbed and harassed by officers in September after she attempted to intervene in an encounter between police and one of her teenage clients.

Last month, Gaston says she took a young man clothes shopping and dropped him off in the Central District. Minutes later, she received a call from the teen, who told Gaston that police had stopped him for jaywalking and accused him of stealing the clothes.

Gaston, who is black, drove to the scene to show the (white) officers the receipt for the clothing.

Gaston says the officers then grabbed and harassed her, and claims that when she tried to call 911, one of the officers involved in the confrontation told the 911 operator to cancel the call. Gaston says officers later called King County Superior Court to complain. She is now being charged with assault for the incident.

Gaston—who not arrested during the incident—has filed a complaint with SPD’s Office of Professional Accountability.
