An Argentine judge has ordered special security measures for Coca-Cola's bottling plants in Argentina, after the company received two telephone calls threatening bomb attacks against company facilities.

The company's lawyers had initially reported the threats to the police in late July after an anonymous caller threatened to bomb their Buenos Aires headquarters, Argentina's state news agency Telam reports.

One caller said he would blow up a bottling plant unless Coke paid US$80,000. It was this call that prompted federal judge Jorge Urso to request the Argentinean security forces to take special precautions to protect the company's offices and production sites.
