"We are working with partners – including the National Cyber Security Centre (NCSC), the Financial Conduct Authority (FCA) and the Information Commissioner’s Office (ICO) – and specialist officers from the NCA’s National Cyber Crime Unit (NCCU) will be working with the company to secure evidence," the agency said in a statement.
"The complexity of these enquiries means this is an investigation which will take time."
