Man dies on plane after ingesting 246 cocaine bags

A Japanese man has died on a flight from Mexico City after ingesting 246 bags of cocaine.

The flight, bound for Japan's Narita International Airport, had to make an emergency landing in Mexico's Sonora state after he began to have seizures.

Authorities said the man, identified as Udo N, died of a cerebral edema caused by a drug overdose.

The passenger transferred to the flight after starting his journey in the Colombian capital Bogotá.

According to a statement by Sonora's attorney general, the bags - measuring 2.5cm long and 1cm wide - were found in his stomach and intestines during the autopsy.
