Anti-death penalty advocates say a British company has supplied the three drugs used to execute death-row inmates to a prison in Arizona, according to AP. Rights group Reprieve says Dream Pharma Ltd., a company run from a London driving school office, shipped sodium thiopental, potassium chloride and pancuronium bromide in September. Reprieve released a copy of the firm's invoice to the Arizona State Prison Complex for 4,253 pounds ($6,584) worth of the three drugs. Two month later, the British government in November banned the export of sodium thiopental for executions. There are no similar restrictions on the other two drugs. Dream Pharma's director, Matt Alavi, declined to comment Thursday.
