Off The Leash is the 266th episode of The Bill.
D.C.s Dashwood and Lines investigate a robbery. The witness is not prepared to give a statement until the gang is caught. Ch. Supt. Brownlow says CID have to liaise with Insp. Monroe. Former Sun Hill typist Delia French starts work as a probationary WPC. Sgt. Peters is puppy-walking her. She loses it when she is checking car registrations and is videotaped by Lines and D.S. Roach. It is Lines's birthday.
Notes
First regular appearance of W.P.C. Delia French (Natasha Williams). She had previously appeared as civilian typist Delia France in Don't Like Mondays before returning to Sun Hill as a probationary constable. For some reason, the character's surname was altered when she joined the regular cast.
