(AP) — A group that opposes alcohol sales in Whiteclay is alleging that one of its beer store owners gave baseball bats and a stick to men who frequent the town, and told them to attack the protesters’ encampment on the Pine Ridge Indian Reservation.

One of those activists was arrested Friday in Lincoln on charges that he vandalized a beer truck in the Nebraska border town. Authorities say 33-year-old Timothy R. McKenzie Jr., of Jefferson, S.D., was arrested on a warrant out of Sheridan County, Neb.

McKenzie alleges in a letter to the Nebraska Liquor Control Commission that Jason Schwarting, owner of the Arrowhead Inn, told men in Whiteclay to attack the nearby encampment.

An Arrowhead Inn employee disputed the allegations, but says Schwarting was not immediately available for comment
