The Sheriff's Office first learned of the incident when an alarmed neighbor on Brookwood Road called to report an intruder in the house at 2:05 p.m.
The man who had fled into the house told deputies that his relative, identified as Milo Imrie, 23, of Richmond, a veteran with combat training, had hit him in the back with a shovel near his home in the area of 150 Wildwood Way, sheriff's spokeswoman Rebecca Rosenblatt said.
The victim was treated for injuries at the scene.
The Sheriff's Office had issued a warning to residents that the perpetrator could still be in the area with the shovel and was potentially dangerous.
Deputies searched the neighborhood and found the suspect at about 4:20 p.m. in the 2300 block of Woodside Road. When deputies tried to take him into custody, he resisted, and deputies used a Taser to subdue him, Ms. Rosenblatt said.
Mr. Imrie, who was taken to a hospital to be treated for his injures and to undergo psychiatric evaluation, is expected to be booked on suspicion of assault with a deadly weapon, Ms. Rosenblatt said.
