In surveillance video, the suspect can be seen hitting the woman across the head at her townhome on Bellaire and Dairy Ashford.
The woman's son, Paul, said she had just gotten home from the gym.
"She felt very lucky that she came out of this with bruises and scrapes, but she's alive," a translator said.
The suspect stole her keys and her silver Honda Accord.
Late Tuesday, police found the stolen vehicle and arrested two people in connection with the crime.
