Police say a man was arrested on suspicion of robbery and assault for severely beating a woman in west Phoenix during a home invasion.
John Eaves is accused of beating the 74-year-old woman as she awoke in her bed early Tuesday morning.
She was bound, and her Mercedes was stolen.
Police say the victim was able to free herself and call for help.
Authorities say the 20-year-old Eaves was spotted driving the victim's car on Thursday, fled from police and later crashed into a parked vehicle.
It's unclear whether Eaves has a lawyer who can comment on his behalf.
The victim is being treated at a hospital for her injuries.
