Bicycle bombs: a further enquiry and a new theory

Has anyone, anywhere, ever, been killed by a pipe bomb disguised as a bicycle? I have been pursuing this question since last June with the help of the Internet and the BBCs Today Programme and World Service. So far the answer appears to be not yet; but it remains in the mind of the Westminster …
