Police said the 24-year-old woman left her daughter in the car while dropping off her 4-year-old son at daycare.
That's when police said a man jumped in the front seat of her car and began to drive off. The mother clung onto the car as the man pulled away.
The girl jumped from the moving vehicle and was taken to the hospital with minor injuries.
But the mother held onto the car until the man pulled over in a parking lot and confronted her.
That's when police said he punched her in the face several times and robbed her before running from the scene.
Police said they hoped releasing the surveillance video would help them catch the suspect.
