• Alleged campaign against laboratory's suppliers
• Court told of vandalism, threats and hoax bombs
...
Under the banner of the Animal Liberation Front and with military precision, five activists carried out an international campaign of blackmail for six years against companies and individuals linked to Huntingdon Life Sciences, a court heard yesterday.

The five - leading members of an organisation called Stop Huntingdon Animal Cruelty (Shac) - menaced men, women and children in England and Europe. They coordinated a blackmail campaign involving hoax bombs, night visits, criminal damage, nuisance phone calls and letters, and threats of physical violence, Michael Bowes QC, prosecuting, told Winchester crown court.

The tactics were terrifying and intended to create a climate of fear to force a string of firms linked to one of the world's largest animal testing laboratories to sever their ties with HLS, Bowes told the court.
