The attack was reported at about 11:45 a.m. Tuesday at a car repair shop in the 1700 block of Ocean Avenue.
A man took his car into the shop to get a flat tire fixed, and a repairman fixed the tire but did not put the hubcap back on, according to police.
The driver and repairman began arguing and pushing each other, and the driver struck the repairman in the face with the hubcap, police said. Officers responded and arrested the man on suspicion of aggravated assault.
His name was not immediately available today, nor was information about injuries to the repairman.
