Several months after the threat first came to light, "Sally" sent out several letter bombs, one of which was received and exploded in the face of the householder, causing her shock and minor injuries, while the Royal Mail intercepted several other packages, which had been held up because insufficient stamps had been put on them. In October 2000, "Sally" threatened to use pipe bombs against Tesco customers and the threat was taken seriously enough that Tesco began the production of the modified Clubcards, but were unable to produce the required number before the deadline set by the blackmailer. In November, "Sally" claimed to have placed a pipe bomb in a garden in the Ferndown area of Dorset. No bomb was found.
