The authority confirmed that the truck was searched at customs and the tablets were found hidden inside a floor cavity where they had spread all over the area.

The authority said that it will continue to tighten customs controls over the Kingdom’s imports, as it works with the General Directorate of Narcotics Control in addressing any attempts at smuggling in order to protect society.

Meanwhile, authorities on Wednesday foiled an attempt to smuggle millions of highly addictive and illegal amphetamine pills into the country.

A top official said that more than 1.9 million Captagon tablets were found hidden in a shipment of iron machines in a warehouse in Riyadh.
