The Department of Transport is warning people of fraudulent "phishing" emails.

The emails are purporting to come from the Department seeking billing information and vehicle details in connection with motor tax transactions.

In a statement, the department says these emails are a hoax and it does not send emails requiring customers to send this type of personal information via email or pop-up windows.

Anyone who receives a suspicious email is being advised to delete it.

The relevant authorities have been contacted.
