A man who died after going into convulsions while flying from Colombia to Japan was found to have swallowed 246 tiny packages of cocaine, officials said.

The man, a 42-year-old Japanese citizen who had begun his journey in Bogota, became ill on an Aeromexico flight from Mexico City to Tokyo which then made an emergency landing very early Friday at Hermosillo airport in the Mexican state of Sonora, according to a statement from the state prosecutor’s office there Monday. He died before medical help could reach him, the prosecutor’s office said.

An autopsy found that he had 246 plastic parcels of less than 1 inch long in his stomach and bowels, the statement said. It determined that his death had been caused by a surge in blood pressure, the result of a drug overdose, probably after one of the parcels ruptured. The man’s name was given in the statement only as Udo N.

The grim discovery was a reminder of the global demand for recreational drugs and of the extreme methods traffickers adopt to satisfy it. Recent reports on the southern U.S. border have detailed smuggling by methods as mundane as mules with backpacks and as elaborate as catapults and compressed-air guns.

But it also highlighted an increasing problem in Colombia. According to data from the U.N. Office on Drugs and Crime, seizures of cocaine in Colombia have increased sharply in the past decade. In 2016, the last available figure, more than 1,100 tons of the drug were seized.

And, in a report released last year, the agency said Colombia had more land used to make cocaine than ever in its history, at 422,550 acres by the end of 2017. Despite a 2016 peace deal between the government and the Revolutionary Armed Forces of Colombia, or FARC, that also sought to discourage the illegal drug trade, the amount of land used to produce coca leaf has gone up on average about 45% a year since 2013, the report said.

The remaining 198 passengers aboard the Aeromexico flight Friday evening continued their journey to Japan.
