Thousands of people have been tricked into signing up to a fake Odeon account after being promised free cinema tickets.
More than 70,000 people have followed the bogus Instagram account in the mistaken belief they would receive a free gift.
The account, which used the Odeon logo, said: "We're new to Instagram so the first 75,000 followers will receive a ticket to see six films."
However, the company has confirmed that the account and the offer are both fake.
