Police were called to Claremont Street in Merrylands about 1.40pm yesterday after a blue Mitsubishi Lancer struck a woman as she was crossing the road.
CCTV shows the car driving away.
The woman in her 40s was found injured on the side of the road before being taken to hospital in an ambulance with a broken leg.
The woman’s two-year-old daughter in the pram was unharmed.
Today police confirmed they seized the unregistered Lancer from a home on Guildford Road at Guildford.
“Police arrested an 82-year-old woman at the scene and took her to Granville Police Station,” NSW Police said in a statement.
“She has since been released without charge, pending further inquiries.”
