Sentencing of Robert Edward Dyer

Date: June 11, 2001 • Location: Welwyn Garden City, United Kingdom

Robert Edward Dyer was sentenced to 16 years' imprisonment for conducting a six-month-long letter-bomb campaign against the British supermarket chain Tesco.

From August 2000 to February 2001, a blackmailer identified by the pseudonym "Sally" threatened the British supermarket chain Tesco with bombing and harming customers if their demands were not met. The blackmailer demanded that Clubcards, modified to allow the withdrawal of cash from ATMs, be left in local newspapers. The attempted extortion started in Bournemouth, England, and led to one of the largest and most secretive operations ever undertaken by Dorset Police.
