Dallas police have released tollway surveillance video showing a woman pushed from a moving car and sprawled on an exit ramp.

Officers are seeking the man, she had just met, who was driving.

Investigators say the incident happened early Sunday as the car was going as fast as 50 mph.

The 19-year-old woman told Dallas police she met the man at a concert and he offered to give her a ride. She says she was shoved from the vehicle when she rejected his sexual advances.

The video also shows another woman running to the victim's aid, getting her to roll to the side of the exit ramp and out of the way of traffic.

Authorities say the victim was treated for severe road rash.

The video was released Wednesday. The victim has asked that her name not be used.
