GARY, Ind. -- A hit and run on the Indiana Toll Road early Sunday morning resulted in a woman being rescued from her vehicle in a water-filled ditch near the Grant Street exit.

According to Indiana State Police, 42-year-old Denise Towner of Gary was driving her red 2000 Chevy Cavalier eastbound when her vehicle was rear ended by another driver.

The impact of the crash caused Towner to lose control of her Cavalier and run off the roadway into a ditch area where the car rolled several times before coming to a rest upside down in waist-deep water.

ISP says a trooper and a Lake County Deputy took off their gear and went into the water, attempting to remover Towner from the vehicle.

The attempt was said to be unsafe because turning the vehicle over or breaking a window could affect the air pocket Towner was using to breathe.

Firefighters eventually freed Towner with the Jaws of Life and transported her to Northlake Hospital for treatment of her injuries.

Troopers say they are still looking for the driver who caused the crash.
