The woman is a current employee of Sage and was nicked at Heathrow airport on suspicion of conspiracy to defraud. She has since been bailed.
It might be a coincidence, but Sage admitted that it had suffered a data breach affecting up to 300 business customers.
Customers have been told that personal and financial information may have been lost during the breach.
The breach was blogged about by consultant Richard De Vere who said only UK customers were affected. The reason it might be connected to the arrest is that De Vere claimed the breach had been the product of an insider threat. To be fair, he never said the arrest was connected so it might be a coincidence.
Sage subsequently stated: “We believe there has been some unauthorised access using an internal login to the data of a small number of our UK customers so we are working closely with the authorities to investigate the situation.”
The company added: “The dedicated helpline number is 0845 145 3345 – please leave a message with your details and we will get back to you as soon as we can. You can also get in touch with us by emailing us at email@example.com.”
