Transport operator Go-Ahead says it has been hit by a cyber security "incident" and says it is investigating the extent of the issue.
In a brief update to shareholders, the Newcastle-based group said it had detected unauthorised activity on its network this week and had quickly hired forensic experts. The firm said it was taking precautionary measures with its IT infrastructure as it worked to understand the nature and extent of the problem.
Business Live was told there was no indication that customer data such as bank account or credit card details had been exposed, and that all payments are handled by accredited third party providers. Go-Ahead also said it was doing everything possible to ensure services continued without interruption and that if any services are affected, customers will be informed via its apps and social media accounts.
