A 32-year-old woman was arrested by the City of London Police last night on suspicion of attempting to defraud software firm Sage.
According to the police force the woman, who is a current employee of Sage, was arrested at Heathrow airport on suspicion of conspiracy to defraud. She has since been bailed.
The arrest comes days after Sage admitted that it had suffered a data breach affecting up to 300 business customers.
Customers were informed that personal and financial information may have been affected by the breach.
Tech consultant Richard De Vere blogged about the breach, which is believed to only affect Sage customers in the UK after he was contacted by customers, and wrote that he believed the breach had been the product of an insider threat.
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 firstname.lastname@example.org." The Register does not have confirmation that the arrest and the breach event are linked. ®
