Activists who want to end beer sales in Whiteclay, Neb., planned a protest Friday after what they described as a showdown with law officers Thursday.
Whiteclay is on the South Dakota border. Critics blame alcohol stores there for problems across the border on the Pine Ridge Indian Reservation, where alcohol is banned.
The group Alcohol Justice says an observance Thursday of the anniversary of the 1973 occupation of Wounded Knee by American Indian Movement activists turned into a showdown with Nebraska troopers. The activists say the troopers withdrew when more than 100 people marched into Whiteclay.
The Nebraska State Patrol said there were no arrests.
Ogallala Sioux President Bryan Brewer said hundreds of people planned to return to Whiteclay Friday.
The Sheridan County Sheriff's Office didn't immediately return telephone calls.
