Hackers are attempting to exploit travellers whose flights were cancelled after a volcano in Iceland erupted earlier this month.

A number of web users have received emails which look like they are from the Civil Aviation Authority and claim travellers can obtain up to £2,000 in compensation if they pay an administration fee.

The email also asks web users to hand over personal information including passport details.

However, a spokesman from the CAA said the emails were fake.

"I can categorically say that this email has nothing to do with us. It's a scam - and we'll be asking the police to investigate," a CAA spokesman told the BBC.

"It's a scam through and through. If you reply, you'll be asked for an 'administration fee' before your payment can be released and you'll never see a penny," warned Charles Conway, editor of the Scam Detectives.

"If you receive an email claiming to be offering you a payment to compensate you for the inconvenience of being stuck overseas, you should delete it immediately without responding."
