Jack Craddock

Jack or Bill Craddock (PROSE: Doctor Who and the Dalek Invasion of Earth) was a survivor of the Daleks' occupation of Earth. Craddock and Mick Thomson were captured by a Roboman patrol and taken to a Dalek saucer. He was put in a cell with the First Doctor and Ian Chesterton after Thomson was killed and told them about the Dalek invasion.

He was released by the rebels when they attacked the saucer but was recaptured and converted into a Roboman. He captured Larry Madison on board the Daleks' saucer and found Ian, and after a brief fight with them, was electrocuted and killed. (TV: The Dalek Invasion of Earth)
