Boone County sheriff�s deputies arrested a Columbia man early Saturday morning on suspicion that he refused to leave an apartment and threatened a man with a gun.

Deputies arrested William R. Harper, 39, after he allegedly pulled a gun from his pocket and hit a resident with the firearm in the 5500 block of Rocky Fork Drive, the sheriff�s department said in a news release. Harper allegedly came to the residence looking for someone and refused to leave, which led to the scuffle, the release said.

The sheriff�s department said the man Harper struck with his gun grabbed his own gun and shot Harper in the arm, and Harper ran from the residence.

Harper was located and taken to a hospital for treatment. Deputies then arrested him and booked him into the Boone County Jail on suspicion of unlawful use of a weapon, third-degree assault and first-degree trespassing on a total bond of $5,500, the release said.
