P.C. Stevens was one of several police officers who came to Coronation Street in pursuit of escaped rapist convict Frank Riley who holed himself up in 14 Coronation Street with Valerie Barlow as his hostage. He and fellow officer PC Jimmie Conway kept low on the walkway outside the flat door, instructed by Detective Constable Bill Sharp, in charge of operations, not to reveal themselves should Riley look out of the window. Conway told Stevens that Ken Barlow was coming over with Sharp and Stevens sympathised with the husband's plight.
When Riley didn't respond the requests to come out conveyed by loudhailer, Sharp got Conway and Stevens to cut the glass of the kitchen window, ringing the flat to cover the noise of the attempt. They were then able to rush in and overpower Riley just as he attempted to leave using Val as a cover.
