PC Bob Walker
Background
Bob Walker is a police constable with the Sandford police department in Sandford, Gloucester. His K9 partner is Saxon.
During the events of Hot Fuzz (2007) played by Karl Johnson
Inspector Frank Butterman takes Nicholas Angel on a tour of the police station and takes Nicholas to the main office where he meets Sergeant Tony Fisher, Bob and Saxon and PC Doris Thatcher. By the time the tour around the department ends it is lunch and they all go out to the pub. They ask Nicholas why he came to Sandford and give him a hard time and assume he came to try and tell them how to do their job. They ask him why he is wearing his stab proof vest and he tells them about when he was stabbed. PC Danny Butterman starts excitedly asking him about the kind of "action" he experienced and DS Andy Wainwright and DC Andy Cartwright tell Nicholas everyone has a weapon in the country. After Martin Blower and Eve Draper's car accident, Nicholas and Danny arrive on scene and Nicholas recommends proper procedure to Tony who then relays it to Bob and Doris. Frank tells Nicholas and Danny he wants them to take Bob and Saxon to investigate a call from Ellroy Farm where Arthur Webley has been cutting hedges that don't belong to him. They go to investigate and when Arthur, who is holding a shotgun, mumbles he only has a license for his shotgun, they find an entire barn full of weapons, including an old sea mine. They take the weapons and bring them to the evidence room after contacting Turner. The entire department goes to Somerfield market and Nicholas accuses Simon of being the murder, but Simon has an alibi and his store footage shows him to be at the store during the day. As Nicholas and Danny are in a shootout with Roy and Mary, they are surrounded by Frank and the rest of the department in riot gear. Nicholas manages to convince the other officers that they have been manipulated and leaves Bob and Saxon to deal with the NWA members in town. Later, as all the officers are doing paperwork, Tom Weaver walks up with a blunderbuss and shoots at Nicholas, but hits Danny who leaps in front of him. Nicholas throws a trash can at Tom and knocks him backwards into the evidence room and the station blows up when the sea mine explodes.
