Fears have been raised in Guinea after armed robbers attack and stole a batch of blood samples infected with the deadly Ebola virus which were being delivered to a test centre. Officials in Guinea say bandits stole a cooler containing blood samples that are believed to be infected with the Ebola virus......

It was reported that the thieves robbed a minibus which was transporting the samples from central Kankan area to the test site 165 miles away... The blood was stored in a sealed container and was being escorted by four Red Cross officials. It is believed the bandits had no idea what it was they were stealing and may have thought there was cash hidden inside the container.

I can imagine the robbers pointing an injection full of infected blood at victims and threatening them: "your money or your life"

Btw, it is Equitoria Guinea that is hosting and not Guinea (Bissau)
