We now know that 51 people were arrested yesterday, but there is one fugitive who needs to be brought to justice. Guido is offering a £1,000 reward for information leading the to the arrest and prosecution of the thug(s) involved in the throwing of the fire extinguisher from the roof of CCHQ yesterday. Aaron Porter is probably too young to remember David Wilkie, killed by a previous generation of left-wing thugs in similar circumstances.

It was just by sheer luck that the fire extinguisher thrown from the roof-top missed a copper or a fellow protestor.

Someone out there knows who was responsible and Guido hopes they have a conscience – email guido.fawkes@order-order.com.

UPDATE : Tim Montgomerie from ConservativeHome has chipped in £100 of the reward, anonymous others have chipped in another £200 or so.
