According to the Sunday Mail, machine gun touting coppers faced off against the Dalek and demanded it put down its plunger and cease to attempting to exterminate anyone.

They need not have worried, for apart from the problem a real Dalek would have had with the stairs at Parliament, this Dalek was an imposter and had a humanoid inside.

The Dalek was being driven by Scot Ken Meikle, 46, who eventually convinced the police that his Dalek's cannon only fired water.

Meikle was in London filming a promotional video for a stage version of Dr Who, after a telling off from the rozzers, he was ordered away from Parliament.
