Police in Bismarck are investigating a fight from Sunday afternoon at Lucky Duck's in Bismarck.

Bismarck Police Sgt. Mark Buschena said a 28-year-old Bismarck man told police he was having lunch with his family when a man approached him, began to argue, then two other men began pushing and assaulting him.

The men reportedly fought their way to the ground and outside, where the man said he tried to give his pocketknife to his father before one of the alleged assailants yelled, grabbed and threw away the knife.

Police arrived to find two men restraining another. One of the men had physical injuries.

Buschena said Monday the matter is under investigation with no arrests.
