- "A great big bushy beard!"
- ―Inspector Butterman talking about Angel's predecessor
Police Sergeant Popwell was a member of the Metropolitan Police Service. He, like Nicholas Angel, was transferred to the rural and "crime-free" area of Sandford. There, he reportedly went mad and killed himself. However, Angel discovered the Neighbourhood Watch Alliance's true intentions and was actually murdered by them. His skeleton was found by Nicholas Angel in the tunnels under Callahoun Park where the rest of the victims rotted.
