A man said he was hit in the head repeatedly with an axe handle wielded by Aaron Foskey when he went to a friend's apartment on Shallowford Road.
Foskey, 40, of 4270 Green Acres Dr., is charged with especially-aggravated robbery.
The victim, who was not named, said he was hit in the head multiple times. He said he believes that two other people may have assisted in the assault.
He said he lost consciousness during the attack, then later woke up.
He said the residents of the apartment, Melissa Turner and Ryan Mooney, arrived home and made Foskey give back the victim's cell phone.
The victim said a friend convinced him to go to the hospital. He was told he had severe contusions and lacerations on his face in multiple places and will need surgery to fix his jaw.
He picked Foskey out of a photo lineup.
