Redford Township police say a woman was sexually assaulted about 4 a.m. Sunday morning after she ran out of gas at 7 Mile and Beech Daly roads.

A man, who she did not know, stopped to help her. He drove her to a gas station at 8 Mile and Beech Daly roads where she got gas.

Then he drove her back to her car and she put the gas in the tank. However, as she began to drive away the vehicle started chugging and she stopped. When she got out of the car the man who had helped her came up from behind with a gun and sexually assaulted her, police say.

Video from the gas station shows the suspect's vehicle. It is dark in color and the rear driver's side wheel is missing its hub cap.
