Fulton County police are investigating the attack early Monday.
WSB-TV reports that the couple had just returned home from a late-night movie and found intruders hiding in their garage.
Authorities say three men, whose faces were covered, attacked the couple and used duct tape to restrain them.
Police say they demanded the code for the safe, and pistol whipped the man and kicked him in the ribs. Authorities say one suspect heated up a curling iron and used it to burn the man's wife.
Police say the husband gave the men the code and they took cash, a computer, a gun and several other items.
