Police said the hapless thief broke into the man's Sydney house yesterday evening and took cash before grabbing the keys to his car.
The proprietor, who was at home at the time with his wife, confronted the thief in the garage as he tried to reverse the vehicle and make a getaway.
After the 68-year-old armed himself with his bow, the intruder opted to get out of the car and make a run for it, jumping a fence.
Despite apparently taking a hit, the man escaped and no trace has been seen of him since.
Police seized the bow and arrow as part of their investigation.
