(Found on Boing Boing) What I find most remarkable about this story is not that it's happened. I can see something like it happening in the States and elsewhere. It's that this bit of silliness is being covered nationally by the BBC:

On Thursday, staff found the plunger arm and a ransom note on a doorstep.

The note read: 'We are holding the Dalek captive. We demand further instructions from the Doctor.'

The group, signing themselves Guardians of the Planet Earth, added: 'For the safety of the human race we have disarmed and removed its destructive mechanism.'

Luckily, Colin Baker (the Sixth Doctor, naturally) is on the case, so hopefully the Dalek will be safely returned to his family soon. Our thoughts are with them.
