SOFIA, May 17 (Xinhua) -- Bulgarian authorities have captured two batches of undeclared hookah tobacco with a total weight of 30 tons, the National Customs Agency (NCA) said in a statement on Friday.

The first batch, split into 14,256 packages weighing 1 kg each, was discovered after an X-ray examination of a Moldova-registered truck when it was leaving Bulgaria at Danube Bridge checkpoint near the town of Vidin at the border with Romania, the statement said.

The two drivers, one with Portuguese and the other with Albanian identity documents, declared to be carrying dried fruit to Western Europe, it said.

The authorities revealed that the truck had been loaded in an illegal warehouse in Sofia and found 15,744 kg of undeclared hookah tobacco there, the statement added.

Last year, the NCA seized more than 5.4 tons of illegal tobacco.
