The man who died was a plumber in his fifties who bought a bottle of the energy drink "Bullwild" in the central Taiwanese city of Taichung. Two others are still in hospital. The concentration of cyanide in their blood is described as very, very high by doctors. The drinks were bought at convenience stores. Each had been labelled "I'm poisonous, don't drink me." But one of the victims said that he didn't notice the label until after he'd taken a sip, others that they thought it was some kind of advertisement. The police say they are searching video footage from security cameras in the shops. It's reported that the tapes show a suspect placing what's believed to be the contaminated drinks back on the shelves.
