On the night of Weds 7th Sept we Brigade G of the Animal Liberation Front detonated a bomb on the doorstep of GlaxoSmithKline director Paul Blakburn, Beaconsfield, Bucks HP9 1PH.
This contained 2 litres of fuel and 4 pounds of explosives. We did this because GSK is a customer of Huntingdon Life Sciences and GSK we realise that this may not be enough to make you stop using HLS, but GSK this is just the beginning.
We have identified and tracked down many of your senior executives and also junior staff, as well as those from other HLS customers.
Drop HLS or you will face the consequences. For all the animals inside HLS, we will be back.
