Three Oak Ridge men have been charged with especially aggravated robbery after a Kingsley Road man was allegedly beaten in the head with a pistol during a drug deal and robbed of $250 on Tuesday afternoon, court records said.

Two of the men were buying Oxycontin at the Kingsley Road home when Nathaniel Tyhiene Johnson, 24, of Bettis Lane, allegedly attacked the victim and beat him in the head with a Raven .25-caliber pistol, Oak Ridge Police Officer Leslie A. Miller said in affidavits filed in Anderson County General Sessions Court.

The victim was treated for serious injuries at Methodist Medical Center and released.

Police found the pistol and a black hoodie and bandana used during the robbery in a black Cadillac on Hillside Road, the affidavits said.

The affidavits said the robbery and attack were allegedly planned by Andre Dominique Fritts, 26, of Wabash Lane, and Bobby Joseph Winn, 25, of Highland Ave., dropped off Johnson near the home “in order to commit the assault and robbery,” court records said.

Fritts, Johnson, and Winn remained jailed in the Anderson County Detention Facility on Thursday morning. Bond has been set at $250,000 for Johnson, and at $500,000 for Fritts and Winn.

Initial court appearances have been set for Nov. 8.
