The Policeman apprehended Sally Webster when she was caught using Alf Roberts's stolen car for her driving test in August 1989.

On the day of the test, Sally was in a rush to get to the test centre as the car she learned in, belonging to Mark Casey, broke down on the way there, forcing Audrey Roberts to volunteer the use of Alf's Volvo instead. As they didn't have time to inform Alf, he assumed the car had been stolen and called the police. The officer was driving a police car which saw the Volvo, signalled them to pull over and arrested Sally, much to the embarrassment of the examiner who was also ordered out of the car. Sally was taken to Weatherfield Police Station, where the matter was cleared up and Alf got a slap on the wrists for wasting police time.
