Hell Pizza has breached ad laws with flyers for its Flaming Dragon promotion, which are full of swear words.

Someone complained about the language used in the circulars, which they say would be attractive to children.

The Advertising Standards Authority has ruled symbols asterisks in place of some of the letters did not suffice.

It's ordered the flyers be removed, but the promotion has wound down and the flyers are out of circulation anyway.

However tens of thousands were sent out with pizzas.
