Credit unions tonight warned about a bogus email being sent to its members.
The electronic message threatens account holders over access to their money if they do not send on personal details.
The Irish League of Credit Unions (ILCU) said the email falsely claims to come from its own account review department.
A spokesman said: “This email is entirely bogus and has not been issued by the Irish League of Credit Unions.”
To assure members, the ILCU said credit unions never ask members to confirm secure log-in details by email.
They have asked anyone who receives the rogue message to delete it immediately and urged members never to provide confidential information by email.
