A man has been charged with blackmailing two employees of a guinea pig farm which became the target of animal rights activists.
Darley Oaks farm was targeted by activists
The 27-year-old from Colchester in Essex was charged at Stafford Police Station with two counts of blackmail.
The charges relate to threatening letters sent to two workers at Darley Oaks Farm in Newchurch, near Burton-on-Trent, Staffs, in 2003.
The man, who is on police bail, is due at Burton magistrates on 5 December.
The farm, which bred guinea pigs for medical research, shut down in January following a six-year campaign by activists.
