A Dalek from Doctor Who was roaming the streets to warn all humans to stay indoors. The alien adversary was an official representative of the fictional Sandford Police Service from the Three Flavours Cornetto trilogy.
All humans must keep indoors.
All humans will self isolate.
By order of the daleks.
As it happens that the people at Police Car Action Vehicles in East Lancashire, England were behind this entertaining but spot-on prank designed for the good of people.
