LONDON (AP) — British customs agents made a creepy discovery when an airline passenger was found with 94 kilograms (207 pounds) of caterpillars in his luggage.

The man claimed they were intended as food for personal consumption.

The U.K. Border Force said Friday that inspectors at London's Gatwick Airport found the dried caterpillars shrink-wrapped in cellophane and packed into hessian bags carried by a passenger travelling from Burkina Faso via Istanbul.

The caterpillars were seized by authorities after the Feb. 23 find because they breached restrictions on importing animal products. The 22-year-old passenger was let off with a warning.

Border Force spokeswoman Ingrid Smith said "the vigilance of our officers has stopped these dried insects from entering the U.K., and possibly posing a risk to our food chain."
