A 53-year-old retired air force brigadier general was arrested yesterday for allegedly threatening to infect a supermarket’s food items with salmonella if he wasn’t paid 310,000 euros, police said. The suspect is said to have sent a letter to a Veropoulos supermarket using language often adopted by terrorist groups in their written communiques. «Imagine what kind of damage you will incur if some unlucky customers found out that they ate hundreds of salmonella bacteria with their meat,» the letter read. The plan involved a female employee who had been appointed the task of handing the suspect an ATM card, at a secret location, that would give access to an account containing the money. Police said the man may have also threatened to spray a hotel with anesthetic gas if he was not paid 210,000 euros.
