- "I think you're talking a load of shit."
- ―Bob Walker
Police Constable Robert "Bob" Walker is the oldest police officer in the Sandford Police Service. He is first met when Nicholas Angel arrives in Sandford and is touring the Sandford Police Station. Throughout all of his appearances, he speaks in an inaudible mumbling sound like Arthur Webley and always has his dog, Saxon, with him. During the shootout near the end of the film, Walker dons riot gear and prepares to arrest Nicholas and Danny, but is convinced not to. He joins their side and fights against the Neighbourhood Watch Alliance but is ordered to patrol the square, rather than join the rest at Somerfield.
