Police said yesterday they have uncovered a case of corporate espionage involving two of the country's top private hospitals. A 34-year-old woman has been arrested after the electronic crimes squad in mid-July caught her sending e-mails of company files to her own personal e-mail address. She had submitted her resignation to the company a few days earlier. The e-mails contained information on hospital clients and financial reports from the accounting department. Police also found two hard disks full of similar files at her home. A further investigation by authorities revealed that she has been an employee of a rival hospital, to which she allegedly passed on all the sensitive information.
