An employee at accounting software company Sage has been arrested in London in connection with an alleged fraud against the company, according to police.

A report by BBC said the 32-year-old Sage employee was apprehended at Heathrow airport on Wednesday. Sage provides cloud-based accounting and business software to organizations in 23 countries around the world.

The woman has been released on bail. City of London police said in a statement that she is a current employee of Sage.

Earlier this week Sage made headlines for an internal security breach, exposing the data of up to 280 U.K.-based customers. The company is working with authorities to investigate, and details of the security incident remain scarce.

Nearly one-quarter of all data breaches are still caused by compromised credentials, according to recent research by the Cloud Security Alliance.
