A 39-year-old man has been arrested in Austria in connection with a case in which rat poison was found in jars of baby food, police say.
Two weeks ago, a jar of carrot and potato purée was found to contain the poison in the eastern state of Burgenland, prompting manufacturer HiPP to recall an entire range of its products.
A total of five contaminated jars were safely recovered in Austria, the Czech Republic and Slovakia before they could be consumed.
Austria's Die Presse newspaper reported that an email demanding €2m (£1.73m) had not been noticed by HiPP until after the ransom deadline expired.
The German firm's CEO told the newspaper the message, which gave the company six days to pay the money, was sent on 27 March to an email address that is checked every two to three weeks.
