"Sigma-Aldrich Chemicals in Dorset, UK have been supplying HLS with chemicals for their filthy experiments for many many years. Now it's pay back time for all the animals that have collapsed in agony after being poisoned with them.

We visited their premises and slashed the tyres of 7 vehicles parked outside (5 belonged to workers still working inside the building) and smashed several of Sigma's windows.

Now the fun begins (for us not you). Not such a good idea dealing with HLS now you are on the receiving end is it scum. Sever HLS's contract NOW. HLS are reeling and we are moving in on all of you. Pay back time is coming down fast.
