A white man accused of opening fire on two Indian immigrants at a Kansas bar in February in a shooting that heightened international concern about American hostility toward foreigners has been indicted on federal hate crime charges, the Justice Department announced Friday.

Adam W. Purinton was kicked out of a bar in Olathe, Kan., on Feb. 22 after patrons complained that he had leveled ethnic slurs at the two men and questioned their immigration status. But Mr. Purinton, 52, soon returned to Austins Bar with a semiautomatic pistol and shot the men, killing one and injuring the other, the authorities said. The gunman also shot a third man who attempted to intervene, striking him in the hand and in the chest, the indictment says.

On Friday, the Justice Department announced that Mr. Purinton had been indicted by a federal grand jury on two hate crime charges and a firearm charge.

The indictment accuses Mr. Purinton of shooting and killing one of the Indian nationals, Srinivas Kuchibhotla, 32, “because of his actual and perceived race, color, religion and national origin.” It also charged that he committed the same crime against the second Indian national, Alok Madasani, who was wounded but survived. Both men worked as engineers for Garmin, a GPS navigation and communications device company.
