CLAYTON • Demonstrators seeking justice for the shooting of an unarmed teen by a Ferguson police officer disrupted the election night party of victorious St. Louis County executive candidate Steve Stenger in a protest that early Wednesday spilled out of a Clayton hotel ballroom and into a downtown street.

Protest organizers say five people were detained in the loud but peaceful demonstration. There was no immediate indication if any charges would be filed.

Police arrested five of the protesters, two men and three women, said Clayton Police Chief Kevin Murphy. Each was charged with peace disturbance and trespassing and released on a summons. The three women arrested and one of the men are from St. Louis. The other man was from Cincinnati.

Demonstrators began filtering into the Sheraton ballroom at the e Sheraton Clayton Plaza ballroom about a half hour after St. Louis County Prosecutor Robert McCulloch arrived and then granted live television interviews from the Stenger reception.
