Customs say they are constantly on the look-out for illegal fireworks

Jim Bevas, of Starburst Fireworks, said youngsters usually got hold of illegal fireworks, rather than those from reputable retailers.

But customs have denied fireworks are making their way into the Channel Islands through back-door routes.

They say their last seizure of illegally imported fireworks occurred two years ago.

Customs and Excise deputy head Mark Lempriere said they were constantly on the look-out for fireworks, but none had been found for quite some time.

"We haven't seized any fireworks, but we are more than happy to hear from the public if they have any information on large quantities of fireworks."

Mr Bevas said new guidelines to raise the age of people allowed to buy fireworks to 20 persecuted the majority for the sake of a small minority of troublemakers.
