A Morrisons employee has been arrested in connection with the company's payroll data theft.
The supermarket giant admitted suffering a data breach last week, which saw the firm's payroll data stolen.
According to reports from Reuters, the grocer was made aware of the theft when data was published on the internet and a disc sent to the Telegraph and Argus newspaper, based in Morrisons' home town of Bradford.
The stolen information included names, addresses and bank account details of staff members, although it was not known at the time how many of its 130,000 employees were affected.
"Initial investigations suggest this theft was not the result of an external penetration of our systems. We can confirm there has been no loss of customer data and no colleague will be left financially disadvantaged," the firm said in a statement, at the time.
"We have already informed our colleagues about the theft and we are helping them take the appropriate actions to safeguard their personal data."
West Yorkshire Police have been supporting Morrisons' investigation into the breach, and confirmed in a statement yesterday that an arrest has now been made.
The suspect is an employee of the company, and has been arrested on suspicion of making or supplying an article for use in fraud.
Gary Hooks, Detective Chief Inspector of protective services at West Yorkshire Police, said: "An employee of Morrisons has been arrested in Leeds this morning [Monday 17 March] in connection with an investigation into the theft of data from the company.
"He is currently in custory," Hooks added.
In the wake of the breach, Morrisons said it would be reviewing its data security measures, and said it has informed banks of the theft and will work with them to maintain account security.
